A race can occur in gpioc_ioctl when it is called with GPIOCONFIGEVENTS
closely followed by GPIOSETCONFIG. GPIOSETCONFIG can alter the
priv->pins list, making it no longer empty and opening the door for
access to priv->events while we are reallocating it. Fix this by holding
priv->mtx while handling GPIOCONFIGEVENTS.
