Don't set flags on the mount structure before all permission checks have
been done.

Don't allow multiple mount operations with MNT_UPDATE at the same
time on the same mount point.  When the first mount operation
completed, MNT_UPDATE was cleared in the mount structure, causing
the second to complete as if it was a no-update mount operation
with the following bad side effects:

        - mount structure inserted multiple times onto the mountlist
        - vp->v_mountedhere incorrectly set, causing next namei
          operation walking into the mountpoint to crash with
          a locking against myself panic.

Plug a vnode leak in case vinvalbuf fails.
