Subject: [patch 1/3 -resend] [SCSI] pmcraid: remove unneeded check

request_size is zero here so this condition is always false.  Also we
already handled negative values some lines earlier so it's not negative
for that reason as well.

It looks like this was introduced because we applied Dan Rosenberg's fix
twice by mistake:
b5b515445f4 "[SCSI] pmcraid: reject negative request size"
5f6279da376 "[SCSI] pmcraid: reject negative request size"
