Subject: [PATCH 03/24] scsi: aacraid: dpcsup: Fix logical bug when !DBG

When DBG is not enabled FIB_COUNTER_INCREMENT() results in an
empty statement, leaving the contents of if() and else() empty.

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

 drivers/scsi/aacraid/dpcsup.c: In function ‘aac_response_normal’:
 drivers/scsi/aacraid/dpcsup.c:105:50: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
 105 | FIB_COUNTER_INCREMENT(aac_config.AsyncRecved);
 | ^
 drivers/scsi/aacraid/dpcsup.c: In function ‘aac_intr_normal’:
 drivers/scsi/aacraid/dpcsup.c:411:30: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body]
 411 | aac_config.AsyncRecved);
 | ^
