From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently variable ret is not initialized and this value is being
returned at the end of the function io_poll_double_wake. Since
ret is not being used anywhere else remove it and just return 0.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: f6e84af0767f ("io_uring: allow POLL_ADD with double poll_wait() users")
