Jinwei Chen a8fe61c936 qcacmn: Prevent runtime PM suspending during hif_force_wake_request ...

Currently if write non-shadow register and not in initial
phase, host will call hif_force_wake_request()-->
pld_force_wake_request_sync(), but this API can not guarantee
MHI/PCIe is in wake state if runtime PM suspending is ongoing
in parallel, later any register accessing through PCIe bus will hit
NOC error.

Add hif_pm_runtime_get_sync() in hif_force_wake_request() to prevent
runtime PM suspending.
