[PATCH] media: mali-c55: free IRQ when remove while runtime-active

["Li Youhong" <dayou5941@163.com>]

From: Li Youhong <liyouhong@kylinos.cn>

The IRQ is requested in runtime_resume() and released in
runtime_suspend(). remove() powers the device off when it is still
runtime-active, but does not free the IRQ.

If the driver is unbound while streaming (or otherwise runtime-active
after a successful resume), the threaded IRQ handler remains registered
against a powered-off device.

Free the IRQ in remove() the same way runtime_suspend() does.

Fixes: 2c9b9bcc2569 ("media: mali-c55: Power-off the peripheral in remove()")
