io_uring: nospec index for tags on files update
[ Upstream commit 34bb77184123ae401100a4d156584f12fa630e5c ]
Don't forget to array_index_nospec() for indexes before updating rsrc
tags in __io_sqe_files_update(), just use already safe and precalculated
index @i.
Fixes: c3bdad0271834 ("io_uring: add generic rsrc update with tags")
