[PATCH 18/20] char device: use _reset_dev_instance() to set 'sin'

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

Internally, use the method to set the 'sin' member variable so that we
don't have to duplicate the g_object_notify() calls, and there are
consistent debug statements whenever this value is modified. This also
means that we need to handle NULL arguments to this function.
