[PATCH] ASoC: max98090: Fix missing free_irq (part 2)

[Jarkko Nikula <jarkko.nikula@linux.intel.com>]

I was blind to see interrupt was requested in codec probe instead of i2c
probe when doing commit 4adeb0ccf86a ("ASoC: max98090: Fix missing free_irq")
and there is still a case where interrupt is kept requested. Although not as
fatal as original issue.

Since codec can be reprobed while driver is loaded the subsequent
max98090_probe() call will fail in interrupt request since it wasn't freed.

Fix this by explicitly freeing irq in max98090_remove().

for-next, I don't think this is critical enough for stable.
