Input: gpio-keys - filter gpio_keys -EPROBE_DEFER error messages

commit ae42f928 ("gpio: Return EPROBE_DEFER if gc->to_irq is NULL")
make gpiod_to_irq() possible to return -EPROBE_DEFER when the racing
happens. This causes the following error message to be printed:

    gpio-keys gpio_keys: Unable to get irq number for GPIO 0, error -517

Fix that by changing dev_err() to dev_err_probe()
