[PATCH 5/6] usb: mtu3: add missing pm_runtime_dont_use_autosuspend() calls

[Joshua Crofts]

The comm_init_err label in mtu3_probe() and mtu3_remove() both call
pm_runtime_disable() on error or device teardown, but don't call
pm_runtime_dont_use_autosuspend(), causing resource leaks.

Add the missing pm_runtime_dont_use_autosuspend().

Found using Coccinelle.

Fixes: df2069acb005 ("usb: Add MediaTek USB3 DRD driver")
Fixes: fa6f59e28c61 ("usb: mtu3: support runtime PM for host mode")
