Subject: [PATCH] aio: remove redundant assignment to variable ret

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

The variable ret is being set to -EINVAL however this is never read
and later it is being reassigned to a new value. The assignment is
redundant and hence can be removed.

Addresses-Coverity: ("Unused Value")
