- Remove incorrect check in RamdiskPnp -- we should only early-quit if the device is removed, not uninitialized, otherwise we'll never get initialized.

Browse Source 
- Add support for IRP_MN_SURPRISE_REMOVAL.
- Handle IRP_MN_QUERY_ID for FDO (it is the first IRP we receive).
- Handle IRP completion for FDOs and forward if necessary.
