scsi: qla2xxx: Fix crash in qla2xxx_mqueuecommand()

RIP: 0010:kmem_cache_free+0xfa/0x1b0
Call Trace:
qla2xxx_mqueuecommand+0x2b5/0x2c0 [qla2xxx]
scsi_queue_rq+0x5e2/0xa40
__blk_mq_try_issue_directly+0x128/0x1d0
blk_mq_request_issue_directly+0x4e/0xb0

Fix incorrect call to free srb in qla2xxx_mqueuecommand(), as srb is now
allocated by upper layers. This fixes smatch warning of srb unintended
free.
