core: fix memory leaks

Since MMModem is an interface and doesn't store stuff like the
modem's physdev internally (since it's an interface) these things
are handled via GObject properties.  And since g_object_get()
returns allocated values, we need to free the returned value
from mm_modem_get_device() after we're done with it.
