[PATCH] revert "swsusp add check for suspension of X controlled devices"

From: Andrew Morton <akpm@osdl.org>

Revert commit ff4da2e262.

It broke APM suspend, probably because APM doesn't switch back to a VT
when suspending.

Tracked down by Matt Mackall <mpm@selenic.com>

Rafael sayeth:
  "It only fixed the theoretical issue that a quick-handed user could
   switch to X after processes have been frozen and before the devices
   are suspended.

   With the current userland suspend tools it shouldn't be necessary."
