Shaun Ruffell 347fe2b225 dahdi_dynamic_loc: Change and check the dyn->pvt pointer under lock. ...

Fixes a crash on unload if the sync_tick callback was running at the same time
the dynamic local span was destroyed. It was possible for
dahdi_dynamic_local_transmit to dereference a pointer that may have already
been freed.
