[PATCH] Revert "io_uring: gate REQ_F_ISREG on !S_ANON_INODE as well"

[Jens Axboe <axboe@kernel.dk>]

This reverts commit 6f11adcc6f36ffd8f33dbdf5f5ce073368975bc3.

The problematic commit was fixed in mainline, so the work-around in
io_uring can be removed at this point. Anonymous inodes no longer
pretend to be regular files after:
