v2: - Only cancel asyncs in close_handle() if this is not a last overall handle. The latter is handled object specific (when object is destroyed later) and differently. Fixes test failure in ntdll/tests/file.c.
This merge request was approved by Zebediah Figura.

if (entry->access & RESERVED_CLOSE_PROTECT) return STATUS_HANDLE_NOT_CLOSABLE; obj = entry->ptr; if (!obj->ops->close_handle( obj, process, handle )) return STATUS_HANDLE_NOT_CLOSABLE;

This doesn't belong in the generic handle code. It should be handled in the close_handle callback of objects that support asyncs.
