g_type_init() has been deprecated (and also marked with the attribute
'deprecated') since glib 2.36 as the type system is automatically
initialized. Since the minimum version of glib required by ModemManager
is 2.36, calling g_type_init() isn't necessarily in the ModemManager
code.
We were trying to load the generic modes supported reported by either *CNTI=2 or
AT+WS46=?, so that then we could filter out the MBM-specific modes unsupported.
But, this may not be ideal, as both these two commands may fail:

Instead, we'll ask the modem for the list of modes supported, and return that
directly.
