scsi: aacraid: Improve code readability

aac_queuecommand() is a scsi_host_template.queuecommand()
implementation.  Any value returned by this function other than one of
the following values is translated into SCSI_MLQUEUE_HOST_BUSY:

* 0
* SCSI_MLQUEUE_HOST_BUSY
* SCSI_MLQUEUE_DEVICE_BUSY
* SCSI_MLQUEUE_EH_RETRY
* SCSI_MLQUEUE_TARGET_BUSY

Improve readability of aac_queuecommand() by returning
SCSI_MLQUEUE_HOST_BUSY instead of FAILED.
