geneve: Remove synchronize_net() in geneve_unquiesce().

When changing the geneve config, geneve_changelink() sandwiches
the config memcpy() between geneve_quiesce() and geneve_unquiesce().

geneve_quiesce() temporarily clears geneve->sock[46] and their
sk_user_data, and then calls synchronize_net() to wait for inflight
fast paths to finish.

geneve_unquiesce() then restores the cleared pointers, but it also
superfluously calls synchronize_net().

The latter synchronize_net() provides no benefit; with or without it,
inflight fast paths can see either the NULL pointers or the original
pointers alongside the new configuration.

Let's remove the redundant synchronize_net() in geneve_unquiesce().
