Greg Kurz b003fc0d8a 9pfs: fix vulnerability in openat_dir() and local_unlinkat_common() 
We should pass O_NOFOLLOW otherwise openat() will follow symlinks and make
QEMU vulnerable.

While here, we also fix local_unlinkat_common() to use openat_dir() for
the same reasons (it was a leftover in the original patchset actually).

This fixes CVE-2016-9602.
