Fix "NOTIFY received when line is idle" deadlock
This can easily be triggered by starting a blind transfer, and hanging
up before the other end has accepted/rejected it, due to the following
path:
- recvd_notify() acquires a read lock on lines_mtx
- cleanup_dead_lines() is called
- A write lock on lines_mtx is acquired
