From: Colin Ian King <[email protected]>

The variable ret is being initialized with a value that is never read
and it is being updated later with a new value.  The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
Fixes: b63534c41e20 ("io_uring: re-issue block requests that failed because of resources")
