[PATCH] ASoC: arizona-jack: Fix runtime PM leak in arizona_start_mic()

[Wentao Liang <vulab@iscas.ac.cn>]

arizona_start_mic() takes a runtime PM reference before enabling mic
detection, but the error path taken when regmap_update_bits_check()
fails returns without releasing it, since pm_runtime_put_autosuspend()
is only called in the !change branch. This leaks a runtime PM reference
whenever the register write fails.

Release the reference on the error path as well.
