ASoC: rsnd: ssiu: add missing .quit callback for gen2

commit c1f847165db50 ("ASoC: rsnd: implement BUSIF related
code in ssiu.c") moved BUSIF related code in ssiu.c
which added .quit callback in ssiu.c to disable error irq
when ssiu quits.

But .quit callback was added only for gen1 and is missing
for gen2, this causes error irq is left enabled after ssiu
quits on gen2.

This commit adds missing .quit callback for gen2
