LU-9507 lnd: Don't Assert On Reconnect with MultiQP

LU-8943 activated the ability to have multiple connections
between peers.  If any of those connections need to be
reconnected (i.e. parameter renegotiation), we were getting
an assert from kiblnd_reconnect_peer() which was not changed
to allow for having multiple connections ongoing at the
same time.

This patch gets rid of the assert from kiblnd_reconnect_peer()
which is no longer valid after LU-8943.
