scsi: aacraid: Fix a couple of small kerneldoc issues

Most likely caused by bitrot (docs not keeping in sync with API).

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/aacraid/linit.c: In function ‘aac_biosparm’:
 drivers/scsi/aacraid/linit.c:368:41: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
 drivers/scsi/aacraid/linit.c:243: warning: Function parameter or member 'shost' not described in 'aac_queuecommand'
 drivers/scsi/aacraid/linit.c:243: warning: Excess function parameter 'done' description in 'aac_queuecommand'
 drivers/scsi/aacraid/linit.c:1176: warning: Excess function parameter 'inode' description in 'aac_cfg_ioctl'
