Hiral Shah db196935d9 fnic: Use the local variable instead of I/O flag to acquire io_req_lock in fnic_queuecommand() to avoid deadloack ... We added changes in fnic driver patch 1.6.0.16 to acquire io_req_lock in fnic_queuecommand() before issuing I/O so that io completion is serialized. But when releasing the lock we check for the I/O flag and this could be modified if IO abort occurs before I/O completion. In this case we wont release the lock and causes deadlock in some scenerios. Using the local variable to check the IO lock status will resolve the problem.
