On RELENG_6, vn_open() will drop Giant aquired for calls into
non-MP-safe filesystem if fdx == -1, assuming the in-kernel callers are
not MP-safe. On HEAD, vn_open() after rev. 1.240 of sys/kern/vfs_vnops.c
would keep the Giant locked when the MPSAFE flag is given.

The difference in the API caused the auditctl() syscall code to try to
unlock non-locked Giant for non-MP-safe filesystems, for instance, UFS
when QUOTA is compiled in.

This is direct commit to RELENG_6 to accomodate for RELENG_6' vn_open().
