[SCSI] bfa: Revert back the current LUN Masking Implementation.
This patch reverts the current LUN Masking Implementation. We re-implemented
this feature using the SCSI Slave Callout's as per the review comments.

[SCSI] bfa: Introduced initiator based lun masking feature.
- Added support to enable initiator based lun masking.
- Initiator based Lun masking works similar to zoning where
initiator port is allowed to see only those LUNs which are
configured to be seen.

[SCSI] bfa: DMA memory allocation enhancement.
- Modified the design such that each BFA sub-module will provide
the amount of DMA and KVA memory needed by it and queues the
same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
needed by all the BFA sub-modules as one contiguous chunk.

[SCSI] bfa: Brocade-1860 Fabric Adapter vHBA support.
- Introduced partitioning of the BFA resources.
- Added h/w queue ID in CPE messages, firmware uses h/w queue ID
from messages to pick a matching RME queue.
- Added message header to bfa_reqq_produce(). h/w queue ID is set
in the message header and firmware modules use h/w queue ID from
message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI
messages. Used to translate host tag to firmware tag. bfa_lpuid()
is changed to bfa_fn_lpu() that encodes both PCI function and port
ID in BFI message header.

[SCSI] bfa: io tag handling and minor bug fix.
Fix iotag handling:
1) Update and check io tag for retry case.
2) Clearing upper 3 bits in io tag when an IO completes.
The 3 upper bits in io tags are used for counting FCP exchange retry.
Un-cleared bits will cause firmware to access invalid memory when the
same io tag is used for an IO to a target that doesn't support FCP
exchange retry.
3) Only check the effective bits when validating an iotag.
Other minor fixes:
1) Added trace to get FC header type with assert of unhandled packet received.
Ignore the type FC_TYPE_FC_FSS (FC_XS).
2) Fixed the adapter info display check - to check for fcmode flag even.

[SCSI] bfa: fix comments for header files
This patch addresses the comments from Randy Dunlap (Randy.Dunlap@oracle.com)
regarding comment blocks that begining with "/**". bfa driver comments
currently do not follow kernel-doc convention, we hence replace all
/** with /* and **/ with */.
