ofproto-dpif: Don't hold mac rwlock while calling send_packet().

Holding the mac learning rwlock while calling send_packet() which
calls xlate_actions() is dangerous because somewhere deep in the chain
the same lock might be acquired causing a deadlock.  Though we haven't
run into this problem in testing, it seems prudent to refactor it.
