[SCSI] bnx2fc: IO completion not processed due to missed wakeup
Driver does not detect a new CQE (completion queue entry) if a thread receives
the wakup when it is in TASK_RUNNING state. Fix is to set the state to
TASK_INTERRUPTIBLE while holding the fp_work_lock.
Also, Use __set_current_task() since it is now set inside a spinlock with
synchronization.
Two other related optimizations:
1. After we exit the while (!kthread_should_stop()) loop, use
__set_current_state() since synchronization is no longer needed.
2. Remove set_current_state(TASK_RUNNING) after schedule() since it
should always be TASK_RUNNING after schedule().
