vfs: fix propagation of atomic_open create error on negative dentry
If ->atomic_open() returns -ENOENT, we take care to return the create
error (e.g., EACCES), if any. Do the same when ->atomic_open() returns 1
and provides a negative dentry.
This fixes a regression where an unprivileged open O_CREAT fails with
ENOENT instead of EACCES, introduced with the new atomic_open code. It
is tested by the open/08.t test in the pjd posix test suite, and was
observed on top of fuse (backed by ceph-fuse).
