expire_signal_quality() may be called after the DBus object skeleton is
removed in mm_iface_modem_shutdown() and before
signal_quality_update_context_free() is called due to the destruction of
the modem object. This patch fixes the issue by canceling any pending
invocation of expire_signal_quality() before the skeleton is removed.
