gpio: tb10x: Fix an error handling path in tb10x_gpio_probe()

Browse source 
[ Upstream commit b547b5e52a ]

If an error occurs after a successful irq_domain_add_linear() call, it
should be undone by a corresponding irq_domain_remove(), as already done
in the remove function.

Fixes: c6ce2b6bff ("gpio: add TB10x GPIO driver")
