mfd: mt6358-irq: Fix missing irq_domain_remove() in error path

[ Upstream commit 384bd58bf7095e4c4c8fcdbcede316ef342c630c ]

If devm_request_threaded_irq() fails after irq_domain_add_linear()
succeeds in mt6358_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_add_linear() to properly release the IRQ domain.
