Johnathan Corgan 9dcc421f6f transport: recover poisoned mutex guards instead of panicking on lock ...

The transport layer used Mutex::lock().unwrap() at ten sites across the
UDP, BLE, and Ethernet code. A std mutex poisons if a thread panics
while holding it, after which every lock().unwrap() on that same mutex
also panics, turning one fault into a cascade. These critical sections
only perform short HashMap/Vec operations on locally constructed values
and are not reachable from peer input, but the idiom is fragile against
any future in-section panic. Replace each with
lock().unwrap_or_else(|e| e.into_inner()), which recovers the guarded
data and removes the cascade with no new dependency and no call-graph
change.

Also replace four self.local_addr.unwrap() calls in the UDP start and
adopt paths with a sentinel fallback. The value is provably set just
above each log line today, but the unwrap is brittle against a future
reordering; logging an unbound sentinel is harmless and cannot panic.
