chase: mask away CHASE_MUST_BE_REGULAR in chase_openat()

We pin the parent directory of the specified directory via CHASE_PARENT,
but if we do that we really should mask off CHASE_MUST_BE_REGULAR,
because a parent dir of course is a dir, nothing else. The
CHASE_MUST_BE_REGULAR after all should apply to the file created in that
dir, not to the parent.
