p2p: clear txreconciliation state for non-wtxid peers

Browse source 
We optimistically pre-register a peer for txreconciliations
upon sending txreconciliation support announcement.
But if, at VERACK, we realize that the peer never sent
WTXIDRELAY message, we should unregister the peer
from txreconciliations, because txreconciliations rely on wtxids.
