lib: Fix unidirectional FRCT traffic handling
Unidirectional traffic has one of the peers only send bare FRCT
packets. These never set a DRF, since they have no sequence number.
At the receiver, all these ACKs and window updates were always dropped
as the receiver connection record was timed out.
Also fixes a SEGV if flow control kicks in (passing NULL timeout to
pthread_cond_timedwait).
