Because of this reason rsnd_mod_interrupt() is searching correspond mod by for loop. But this loop is not needed, because each mod has own type. This patch avoid pointless loop by using mod->type. This patch is good for SSI-parent support, because stream might have 2 SSI as SSI-parent/child. SSI interrupt handler will be called twice if stream has SSI-parent without this patch.
