checkMobileProvisioning should not block.

In checkMobileProvisioning the call to mdst.isProvisioningNetwork() is
a blocking call and during monkey testing without SIM this is causing
ANR's. Move the initial test for provisioning into isMobileOk so
checkMobileProvisioning doesn't block.

If mobile is not supported return CMP_RESULT_NO_CONNECTION.

Cleaned up some debug.
