scsi: megaraid: Return SCSI_MLQUEUE_HOST_BUSY instead of 1

.queuecommand() implementations are expected to return a SCSI_MLQUEUE_*
value. Return SCSI_MLQUEUE_HOST_BUSY from megaraid_queue_lck() instead
of 1. This patch doesn't change any functionality since
scsi_dispatch_cmd() converts all return values other than SCSI_MLQUEUE_*
into SCSI_MLQUEUE_HOST_BUSY.
