bus: mhi: host: pci_generic: Add pm_runtime_forbid() in remove callback
Add pm_runtime_forbid() to balance the pm_runtime_allow() call made
during Mission Mode transition. Without this, the device remains in runtime
PM allowed state even after driver removal.
Fixes: 855a70c12021 ("bus: mhi: Add MHI PCI support for WWAN modems")
