Tetsuo Handa dd2a5b5514 mm/util: make memdup_user_nul() similar to memdup_user() 
Since the string data to copy from userspace is likely less than PAGE_SIZE
bytes, replace GFP_KERNEL with GFP_USER like commit 6c2c97a24f09
("memdup_user(): switch to GFP_USER") does and add __GFP_NOWARN like
commit 6c8fcc096be9 ("mm: don't let userspace spam allocations warnings")
does.  Also, use dedicated slab buckets like commit d73778e4b867
("mm/util: Use dedicated slab buckets for memdup_user()") does.
