Executing a reset each time the modem is unbound is a bit too extreme: the modem sometimes recovers by itself and only needs a "soft" reset sequence (unbind/bind). This commit introduces a short timer (2s) so we the modem can settle in. If reset fails after this time, the modem is probably completely broken, or already rebooting, so we can safely issue a reset AT command.
