scripts/checkpatch.pl: __GFP_NOFAIL isn't going away

Revert commit 7e4915e ("checkpatch: add warning of future __GFP_NOFAIL use"). There are no plans to remove __GFP_NOFAIL. __GFP_NOFAIL exists to a) centralise the retry-allocation-for-ever operation into the core allocator, which is the appropriate implementation site and b) permit us to identify code sites which aren't handling memory exhaustion appropriately.
