Subject: [PATCH][next] block/mq-deadline: remove redundant assignment of variable ret

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

Variable ret is being assigned a value at the end of the function
and the value is never read. The assignment is redundant and can
be removed.

Addresses-Coverity: ("Unused value")
