fixed rar_Hopping configuration for eMTC. The value in configuration file was a string, but libconfig was told it was an int. changed the configura
tion file to '1' for this parameter and put default value to '1' which means off. Added AssertFatal, if this value is '0', which we don't suppor fo
r now.
