Holger Schurig 40e6fa829a libertas: don't retry commands
Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.

Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.
