Subject: [PATCH -next] io_uring: remove set but not used variable 'ret'

Fixes gcc '-Wunused-but-set-variable' warning:

fs/io_uring.c: In function io_ring_submit:
fs/io_uring.c:2279:7: warning: variable ret set but not used [-Wunused-but-set-variable]

It's not used since commit f3fafe4103bd ("io_uring: add support for sqe links")
