slub: fix high order page allocation problem with __GFP_NOFAIL
SLUB already try to allocate high order page with clearing __GFP_NOFAIL.
But, when allocating shadow page for kmemcheck, it missed clearing
the flag. This trigger WARN_ON_ONCE() reported by Christian Casteyde.

https://lkml.org/lkml/2013/12/3/764
This patch fix this situation by using same allocation flag as original
allocation.
