Subject: [PATCH] nvme-fabrics: remove some logically dead code performing redundant ret checks

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

The check to see if ret is non-zero and return this rather than count
is redundant in two occassions.  It is redundant because prior to this
check, the return code ret is already checked for a non-zero error
return value and we return from the function at that point.
