rS365761: Rename unp_pcb_lock2().

Summary

I think unp_pcb_lock_pair() is a better name. Also make it handle the
case where the two sockets are the same instead of forcing callers to do
it. No functional change intended.

sys/kern/uipc_usrreq.c
752–753	Might not be a bad idea to (perhaps later) introduce a unp_pcb_unlock_pair for these cases, if for nothing but the symmetry of lock_pair/unlock_pair to make it easier to verify correctness.
