Routine Description:
This routine is called to queue a request to either the async or delayed
close queue. For the delayed queue we need to allocate a smaller
structure to contain the information about the file object. We do
that so we don't put the larger IrpContext structures into this long
lived queue. If we can allocate this structure then we put this
on the async queue instead.
Arguments:
Fcb - Fcb for this file object.
UserReference - Number of user references for this file object. This is
zero for an internal stream.
DelayedClose - Indicates whether this should go on the async or delayed
close queue.
Return Value:
None
