[PATCH RFC/RFT 03/15] gpio: sysfs: call mutex_destroy() in gpiod_unexport()

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

While not critical, it's useful to have the corresponding call to
mutex_destroy() whenever we use mutex_init(). Add the call right before
kfreeing the GPIO data.
