xen/tmem: s/disable_// and change the logic.
The variety of disable_[cleancache|frontswap|selfshrinking] are making this a bit complex. Just remove the "disable_" part and change the logic around for the "nofrontswap" and "nocleancache" parameters. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
