kfence: skip __GFP_THISNODE allocations on NUMA systems
commit e64f81946adf68cd75e2207dd9a51668348a4af8 upstream.
On NUMA systems, __GFP_THISNODE indicates that an allocation _must_ be on
a particular node, and failure to allocate on the desired node will result
in a failed allocation.
Skip __GFP_THISNODE allocations if we are running on a NUMA system, since
KFENCE can't guarantee which node its pool pages are allocated on.
