cpuset: Remove set but not used variable 'cs'
Fixes gcc '-Wunused-but-set-variable' warning:
kernel/cgroup/cpuset.c: In function 'cpuset_cancel_attach':
kernel/cgroup/cpuset.c:2167:17: warning:
variable 'cs' set but not used [-Wunused-but-set-variable]
It never used since introduction in commit 1f7dd3e5a6e4 ("cgroup: fix handling
of multi-destination migration from subtree_control enabling")
