[PATCH] altair: Mark SIM provisioned in load_subscription_state

[Prathmesh Prabhu]

An unknown --> home (roaming) registration state change is not visible to the
plugin until mm_iface_modem_3gpp_reload_current_registration_info completes.
This causes the subscription state check during registration to miss the fact
that registration was successful.

load_subscription_state is intended to check subscription state
post-registration. As an initial implementation, mark the SIM provisioned in
absence of more information post-registration.
