cgroup/rstat: desc member cgrp in cgroup_rstat_flush_release

Recent change to cgroup_rstat_flush_release added a
parameter cgrp, which is used by tracepoint to correlate
with other tracepoints that also have this cgrp.

The kernel test robot detected kernel doc was missing
a description of this member.
