qla2xxx: Fix endianness of task management response code
commit e4b11b89f9039ca97b2ed1b6efeb6749fbdeb252 upstream. The qla2xxx firmware actually expects the task management response code in a CTIO IOCB with SCSI status mode 1 to be in little-endian byte order, ie the response code should be the first byte in the sense_data[] array. The old code erroneously byte-swapped the response code, which puts it in the wrong place on the wire and leads to initiators thinking every task management request succeeds (since they see 0 in the byte where they look for the response code).
