vol: fix CreateFile params nt_unlink and nt_open
nt_unlink: when opening a file handle to assign delete on close
status the caller must request DELETE permission.
nt_open: make sure that DELETE permission along with FILE_SHARE_DELETE
is requested if we wish to permit another CreateFile call in the future
to assign delete on close.
