scsi: aic94xx: Fix a couple of formatting and bitrot issues

Kerneldoc format should be '@.*: ', else the checker gets confused.

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

 drivers/scsi/aic94xx/aic94xx_scb.c:137: warning: Function parameter or member 'phy' not described in 'asd_get_attached_sas_addr'
 drivers/scsi/aic94xx/aic94xx_scb.c:137: warning: Function parameter or member 'sas_addr' not described in 'asd_get_attached_sas_addr'
 drivers/scsi/aic94xx/aic94xx_scb.c:860: warning: Function parameter or member 't' not described in 'asd_ascb_timedout'
 drivers/scsi/aic94xx/aic94xx_scb.c:860: warning: Excess function parameter 'data' description in 'asd_ascb_timedout'
