Unbreak MNT_UPDATE when running with cd as root.  Detect mountroot by
checking for "path == NULL" (like ffs) rather than MNT_ROOT.  Otherwise
when you try and do an update or mountd does an NFS export, the remount
fails because the code tries to mount a fresh rootfs and gets an EBUSY.
The same bug is in 4.x (which is where I found it).

Sanity check by: mux
