huawei: fix SIM state notification when locked 

When SIM is locked, huawei modem does not send any notification about
SIM state change because it does not differentiate 'invalid' from
'locked'.

In order to be able to unlock the sim, this patch forces a notification
of a valid state after a timeout.
