The problem happens when a v3 mount fails with ETIMEDOUT after
the v4 mount failed with EPROTONOSUPPORT, in mount auto negotiation.
It immediately breaks from the "for" loop in nfsmount_fg()
or nfsmount_child() due to EPROTONOSUPPORT, never doing the expected
retries until timeout.

Let's retry in v3, too.
