BUG/MEDIUM: connections: Don't forget to unlock when killing a connection.

Browse Source 
Commit 140237471e408736bb7162e68c572c710a66a526 made sure we hold the
toremove_lock for the corresponding thread before removing a connection
from its idle_orphan_conns list, however it failed to unlock it if we
found a connection, leading to a deadlock, so add the missing deadlock.

This should be backported to 2.1 and 2.0.
