UBIFS: use GFP_NOFS properly
This patch fixes a brown-paperbag bug which was introduced by me: I used incorrect "GFP_KERNEL | GFP_NOFS" allocation flags to make sure my allocations do not cause write-back. But the correct form is "GFP_NOFS". Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
