Subject[PATCH v3] mm/oom_kill: remove comment and rename is_dump_unreclaim_slabs()
Comment for is_dump_unreclaim_slabs is not really clear whether it is
meant to instruct how to use the function or whether it is an outdated
information of the past implementation of the function. it doesn't realy
help that is_dump_unreclaim_slabs is hard to grasp on its own.

Rename the helper to should_dump_unreclaim_slabs which should make it
clear what it is meant to do and drop the comment as the purpose
should be pretty evident now.
