Konstantin Belousov dd0f9532f3 Do the vput() for the lowervp in the null_nodeget() for error case too.
Several callers of null_nodeget() did the cleanup itself, but several
missed it, most prominent being null_bypass(). Remove the cleanup from
the callers, now null_nodeget() handles lowervp free itself.
