Jonathan Santos e5b7ad8119 gprs: Reset LLC state when Timer 3350 expires
This works around a problem that occurs if a mobile loses packet
data connectivity, e.g. moves out of coverage or switches over
to a circuit-switched call, while a data transfer is occurring.
The mobile would reset its LLC state, causing it to be
unsynchronized with the SGSN.  Therefore the SGSN would drop
incoming frames until the sequence numbers matched.  This
workaround resets the LLC state in the SGSN if T3350 expires,
indicating that Routing Area Updating Request, Attach Request,
or P-TMSI Realloc Command has failed.
