[GIT PULL] vfs fixes

[Christian Brauner]

Hey Linus,

/* Summary */
During the pipe nonblock rework that made it in the check for both
O_NONBLOCK and IOCB_NOWAIT was dropped. Both checks need to be performed
to ensure that files without O_NONBLOCK but IOCB_NOWAIT don't block when
writing to or reading from a pipe.

This just contains the fix adding the check for IOCB_NOWAIT back in.

---

On a personal note, I'm still traveling because of LSFMMBPF (I'm
probably missing 5 letters and rearranging 3) and LSS
and will only be back on a regular schedule starting Tuesday.

/* Testing */
clang: Ubuntu clang version 15.0.6
gcc: (Ubuntu 12.2.0-3ubuntu1) 12.2.0

All patches are based on 6.4-rc1 and have been sitting in linux-next.
No build failures or warnings were observed. All old and new tests in
fstests, selftests, and LTP pass without regressions.

/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with
current mainline.
