scsi: qla2xxx: Fix incorrect reporting of task management failure

Browse Source 
commit 58ca5999e0367d131de82a75257fbfd5aed0195d upstream.

User experienced no task management error while target device is responding
with error. The RSP_CODE field in the status IOCB is in little endian.
Driver assumes it's big endian and it picked up erroneous data.

Convert the data back to big endian as is on the wire.
