Askar Safin ef84ddf89d openat2: don't trigger automounts with RESOLVE_NO_XDEV 
commit 042a60680d upstream.

openat2 had a bug: if we pass RESOLVE_NO_XDEV, then openat2
doesn't traverse through automounts, but may still trigger them.
(See the link for full bug report with reproducer.)

This commit fixes this bug.
