Vlastimil Babka (SUSE) 6dbded46e4 mm/slab: allow __GFP_NOMEMALLOC and __GFP_NOWARN for kmalloc_nolock() ...

The two flags are added internally so there's no point for warning if
they are passed by the caller as well, so allow them. This will allow
simplifying obj_ext allocation under kmalloc_nolock().

Also it's not necessary to have the extra alloc_gfp variable for adding
the two flags. The original gfp_flags parameter is not used anywhere
except for the warning. So remove alloc_gfp and directly modify and use
gfp_flags everywhere.
