Log Message:
Fix obvious bugs:
* The MNT_UPDATE case had a null pointer dereference.  (This is a good example
of why blindly adding bogus initializiers is a FUNDAMENTALLY BAD IDEA!)
* Make sure the whole ufsmount is zeroed, as the export code relies on this.
* If we decided to use the second/alternate superblock, make sure to copy the
in-core version from the right buffer.
Also, reenable NFS exporting.
