[PATCH] vmalloc(): don't pass __GFP_ZERO to slab

Browse source 
A recent change to the vmalloc() code accidentally resulted in us passing
__GFP_ZERO into the slab allocator.  But we only wanted __GFP_ZERO for the
actual pages whcih are being vmalloc()ed, and passing __GFP_ZERO into slab is
not a rational thing to ask for.
