[NTFS]

Add two more flags (mutually exclusive) for IRP context:
- _COMPLETE will cause the IRP to be completed at the end of the dispatch, with the run-time priority boost set by caller
- _QUEUE will cause the IRP to be queued for delayed execution (not yet implemented)

This allows more flexibility for callers that can set the behavior thanks to the flags.
Default behavior is the previous one: by default the IRP is completed at the end of the dispatch

That one should really come to FastFAT...
