Enable USSD_STATE_USER_ACTION

If the network requests user action in the response to an MO USSD, we
cannot immediately return to USSD_STATE_USER_IDLE. Instead,
USSD_STATE_USER_ACTION is entered.

Note that it is left up to the driver to notify() when the USSD
transaction is closed by the network due to inactivity. Another way to
return to USSD_STATE_IDLE is for the user to cancel() the transaction.
