Temporarily lock Giant while we update td_ucred.  The proc lock doesn't
fully protect p_ucred yet so Giant is needed until all the p_ucred
locking is done.  This is the original reason td_ucred was not used
immediately after its addition.  Unfortunately, not using td_ucred is
not enough to avoid problems.  Since p_ucred could be stale, we could
actually be dereferencing a stale pointer to dink with the refcount, so
we really need Giant to avoid foot-shooting.  This allows td_ucred to
be safely used as well.
