gpio: tb10x: Fix an error handling path in tb10x_gpio_probe()
[ Upstream commit b547b5e52a0587e6b25ea520bf2f9e03d00cbcb6 ]
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: c6ce2b6bffe5 ("gpio: add TB10x GPIO driver")
