USB: HWA: fix device probe failure
This patch fixes a race condition that caused the HWA_HC interface probe
function to occasionally fail. The HWA_HC would attempt to register
itself with the HWA_RC by searching for a uwb_rc class device with the
same parent device ptr. If the probe function for the HWA_RC interface
had yet to run, the uwb_rc class device would not have been created
causing the look up to fail and the HWA_HC probe function to return an
error causing the device to be unusable.
The fix is for the HWA to delay registering with the HWA_RC until
receiving the command from userspace to start the wireless channel. It
is the responsibility of userspace to ensure that the uwb_rc class
device has been created before starting the HWA channel.

uwb: improved MAS allocator and reservation conflict handling
Greatly enhance the MAS allocator:
- Handle row and column reservations.
- Permit all the available MAS to be allocated.
- Follows the WiMedia rules on MAS selection.
Take appropriate action when reservation conflicts are detected.
- Correctly identify which reservation wins the conflict.
- Protect alien BP reservations.
- If an owned reservation loses, resize/move it.
- Follow the backoff procedure before requesting additional MAS.
When reservations are terminated, move the remaining reservations (if
necessary) so they keep following the MAS allocation rules.

uwb: reference count reservations
Reference counting the struct uwb_rsv's is safer and easier to get right than
the transferring ownership of the structures from the PAL to reservation
manager.
This fixes an oops in the debug PAL after a reservation timed out.
