Change updateVoNrSettings() to check the state of of the IccCard instead of mSimState

If GsmCsmaPhone processes CARRIER_CONFIG_CHANGED before SIM_APPLICAION_STATE_CHANGED then mSimState will not be updated with the state SIM_STATE_NOT_READY.

getIccCard().getState() will have the most recent state, so we will check that instead.
