mfd: mt6397-irq: Fix missing irq_domain_remove() in error path

Browse Source 
[ Upstream commit b4b1bd1f33 ]

If devm_request_threaded_irq() fails after irq_domain_create_linear()
succeeds in mt6397_irq_init(), the function returns without removing
the created IRQ domain, leading to a resource leak.

Call irq_domain_remove() in the error path after a successful
irq_domain_create_linear() to properly release the IRQ domain.
