[PATCH] dbus-vmstate: replace g_return with error handling

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Since g_input_stream_read_all() may return less than requested when the
stream is malformed, we should treat this condition as a runtime user
error (g_return are for programming errors).
