mm, oom: header nodemask is NULL when cpusets are disabled
Commit 82e7d3abec86 ("oom: print nodemask in the oom report") implicitly
sets the allocation nodemask to cpuset_current_mems_allowed when there
is no effective mempolicy. cpuset_current_mems_allowed is only
effective when cpusets are enabled, which is also printed by
dump_header(), so setting the nodemask to cpuset_current_mems_allowed is
redundant and prevents debugging issues where ac->nodemask is not set
properly in the page allocator.
This provides better debugging output since
cpuset_print_current_mems_allowed() is already provided.
