scsi: qla2xxx: Fix incorrect reporting of task management failure

commit 58ca5999 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.
