[PATCH] scsi: pmcraid: remove redundant check to see if request_size is less than zero

[PATCH] scsi: pmcraid: remove redundant check to see if request_size is less than zero

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

The 2nd check to see if request_size is less than zero is redundant
because the first check takes error exit path on this condition. So,
since it is redundant, remove it.

Detected by CoverityScan, CID#146149 ("Logically Dead Code")
