ASoC: rsnd: avoid duplicate free_irq()

commit e0936c3 upstream.

commit 1f8754d ("ASoC: rsnd: don't call free_irq() on
Parent SSI") fixed Parent SSI duplicate free_irq().
But on Renesas Sound, not only Parent SSI but also Multi SSI
have same issue.
This patch avoid duplicate free_irq() if it was not pure SSI.
