[PATCH 1/6] io_uring: fix spurious fput in registered ring path

[Jens Axboe <axboe@kernel.dk>]

Fix an issue with io_uring_ctx_get_file() not gating fput() on whether
or not the file descriptor is a registered/direct one or not.

Fixes: c5e9f6a96bf7 ("io_uring: unify getting ctx from passed in file descriptor")
