Let ntvfs request transport close via ntvfs_request state
[I can't swear that this covers all the smb2 cases, there are some reply
functions that I can't trace properly]
Add NTVFS_ASYNC_STATE_CLOSE bit to ntvfs_request->async_states->state
so that the ntvfs layer can signify that the client transport should
be closed, most useful for proxy servies, and most likely due to a
forwarding transport having been closed.
