[PATCH] scsi: aacraid: remove redundant zero check on ret

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The check for ret being zero is redundant as a few statements earlier
we break out of the while loop if ret is non-zero.  Thus we can
remove the zero check and also the dead-code non-zero case too.

Detected by CoverityScan, CID#1411632 ("Logically Dead Code")
