Subject: [PATCH][V2] scsi: aacraid: rcode is unsigned and should be signed int

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

aac_fib_send can return -ve error returns and hence rcode should
be signed. Currently the rcode >= 0 check is always true and -ve
errors are not being checked.

Thanks to Dan Carpenter for spotting my original broken fix to this
issue.
