scsi: fnic: Replace sgreset tag with max_tag_id
sgreset is issued with a SCSI command pointer. The device reset code
assumes that it was issued on a hardware queue, and calls block multiqueue
layer. However, the assumption is broken, and there is no hardware queue
associated with the sgreset, and this leads to a crash due to a null
pointer exception.
Fix the code to use the max_tag_id as a tag which does not overlap with the
other tags issued by mid layer.
Tested by running FC traffic for a few minutes, and by issuing sgreset on
the device in parallel. Without the fix, the crash is observed right away.
With this fix, no crash is observed.
