ipn/ipnlocal: fix nil control client panic while updating TKA head
As part of tailnet-lock netmap processing, the LocalBackend mutex
is unlocked so we can potentially make a network call. Its possible
(during shutdown or while the control client is being reset) for
b.cc to become nil before the lock is picked up again.
Fixes: #9554
