Quinn Tran 82d8dfd2a2 scsi: qla2xxx: edif: Fix performance dip due to lock contention 
User experienced performance dip on measuring IOPS while EDIF
enabled. During I/O time, driver uses dma_pool_zalloc() call to allocate a
chunk of memory. This call contains a lock behind the scene which
contribute to lock contention. Save the allocated memory for reuse and
avoid the lock.
