Input: gpio-keys - fix possible concurrent access in gpio_keys_irq_timer()
gpio_keys_irq_isr() and gpio_keys_irq_timer() access the same resources.
There could be a concurrent access if a GPIO interrupt occurs in parallel
of a HR timer interrupt.
Guard back those resources with a spinlock.
Fixes: 019002f20cb5 ("Input: gpio-keys - use hrtimer for release timer")
