During the dmem cgroup development, the parameters to the
dmem_cgroup_state_evict_valuable() and dmem_cgroup_try_charge() were
changed, but the documentation wasn't adjusted accordingly.
This results in a documentation build warning. Adjust the documentation
to reflect what the final functions parameters are.
