[SCSI] aic94xx: SATA tag mask not set correctly
The aic94xx controller has a bitmask establishing which tags are ok to
use with a SATA NCQ disk. When the queue depth is 32, however, the
expression that is used sets the mask to zero, not 0xFFFFFFFF.
This patch widens the width of the integer so that this case is handled
properly.
