[PATCH v2 2/2] bus: mhi: host: pci_generic: Add pm_runtime_forbid() in remove callback

[Qiang Yu]

Add pm_runtime_forbid() to balance the pm_runtime_allow() call made
during probe. Without this, the device remains in runtime PM allowed
state after driver removal.

Fixes: 855a70c12021 ("bus: mhi: Add MHI PCI support for WWAN modems")
