qcacld-3.0: request runtime sync resume while removing driver

When __hdd_soc_remove is called from platform driver, for
removing the driver, request runtime sync resume before setting
unload_in_progress flag, such that runtime resume can happen.
Also, remove wlan_hdd_validate_context to skip unload_in_progress
flag check and have only SSR check during resume callback.
