gpio: regmap: Fix memleak in error path in gpio_regmap_register()

Call gpiochip_remove() to free the resources allocated by
gpiochip_add_data() in error path.

Fixes: 553b75d ("gpio: regmap: Allow to allocate regmap-irq device")
Fixes: ae49581 ("gpio: regmap: add the .fixed_direction_output configuration parameter")
