[RFC PATCH] Fixes and cleanups to the tmem driver. (v1)

[Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>]

These patches are RFC - I hadn't yet completly tested them. But they
fix the annoying:
 drivers/xen/tmem.c:365:13: warning: 'disable_frontswap_selfshrinking' defined but not used [-Wunused-variable]

(patch #4: [PATCH 4/8] xen/tmem: Fix compile warning. does it).

The rest are cleanups and removes some of the #ifdef machinary.

I hadn't yet the full testing and I am sure I am missing some
other documentation I should update.
