ASoC: fsl_micfil: Enable default case in micfil_set_quality()
commit a8c9a453387640dbe45761970f41301a6985e7fa upstream.
If 'micfil->quality' received from micfil_quality_set() somehow ends
up with an unpredictable value, switch() operator will fail to
initialize local variable qsel before regmap_update_bits() tries
to utilize it.
While it is unlikely, play it safe and enable a default case that
returns -EINVAL error.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
