Windows: AFS_INVALIDATE_DELETE must cancel IO

Browse Source 
When processing an AFS_INVALIDATE_DELETE the redirector
must cancel any outstanding extent requests on the file
prior to tearing down the extents.

This code path is triggered either when VNOVNODE is received
from a file server or when an alternate cache manager interface
(SMB) unlinks the file.
