ALSA: ice1712: Do not left ice->gpio_mutex locked in aureon_add_controls()
If snd_ctl_add() fails in aureon_add_controls(), it immediately returns
and leaves ice->gpio_mutex locked. ice->gpio_mutex locks in
snd_ice1712_save_gpio_status and unlocks in
snd_ice1712_restore_gpio_status(ice).
It seems that the mutex is required only for aureon_cs8415_get(),
so snd_ice1712_restore_gpio_status(ice) can be placed
just after that. Compile tested only.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
