wimax/i2400m: remove an unused variable
"result" isn't used. We ignore errors here because there is not much we
can do about them.

wimax/i2400m: handle USB stalls
When the device stalls, clear it and retry; if it keeps failing too
often, reset the device.
This specially happens when running on virtual machines; the real
hardware doesn't seem to trip on stalls too much, except for a few
reports in the mailing list (still to be confirmed this is the cause,
although it seems likely.
NOTE: it is not clear if the URB has to be resubmitted fully or start
only at the offset of the first transaction sent. Can't find
documentation to clarify one end or the other.
Tests that just resubmit the whole URB seemed to work in my
environment.

wimax/i2400m: Fix USB timeout specifications (to ms from HZ)
The USB code was incorrectly specifiying timeouts to be in jiffies vs
msecs. On top of that, lower it to 200ms, as 1s is really too long
(doesn't allow the watchdog to trip a reset if the device timesout too
often).

wimax/i2400m: fix oops caused by race condition when exiting USB kthreads
Current i2400m USB code had to threads (one for processing RX, one for
TX). When calling i2400m_{tx,rx}_release(), it would crash if the
thread had exited already due to an error.
So changed the code to have the thread fill in/out
i2400mu->{tx,rx}_kthread under a spinlock; then the _release()
function will call kthread_stop() only if {rx,tx}_kthread is still
set.

wimax/i2400m: USB driver uses a configurable endpoint map
Newer generations of the i2400m USB WiMAX device use a different
endpoint map; in order to make it easy to support it, we make the
endpoint-to-function mapeable instead of static.

i2400m/USB: TX and RX path backends
Implements the backend so that the generic driver can TX/RX to/from
the USB device.
TX is implemented with a kthread sitting in a never-ending loop that
when kicked by the generic driver's TX code will pull data from the TX
FIFO and send it to the device until it drains it. Then it goes back
sleep, waiting for another kick.
RX is implemented in a similar fashion, but reads are kicked in by the
device notifying in the interrupt endpoint that data is ready. Device
reset notifications are also sent via the notification endpoint.
We need a thread contexts to run USB autopm functions (blocking) and
to process the received data (can get to be heavy in processing
time).
