[PATCH 2/6] usb: xhci-mtk: add missing pm_runtime_dont_use_autosuspend() call

[Joshua Crofts]

The disable_pm label in xhci_mtk_probe() and xhci_mtk_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: 0cbd4b34cda9 ("xhci: mediatek: support MTK xHCI host controller")
Fixes: 04284eb74e0c ("usb: xhci-mtk: add support runtime PM")
