slab: remove GFP_THISNODE clearing from alloc_slabmgmt()
Commit 6cb062296f73e74768cca2f3eaf90deac54de02d ("Categorize GFP flags")
left one call-site in alloc_slabmgmt() to clear GFP_THISNODE instead of
GFP_CONSTRAINT_MASK. Unfortunately, that ends up clearing __GFP_NOWARN
and __GFP_NORETRY as well which is not what we want. As the only caller
of alloc_slabmgmt() already clears GFP_CONSTRAINT_MASK before passing
local_flags to it, we can just remove the clearing of GFP_THISNODE.
This patch should fix spurious page allocation failure warnings on the
mempool_alloc() path. See the following URL for the original discussion
of the bug:
