[PATCH] selftests/cgroup: fix string comparison in write_test

[Hongfu Li]

Use string comparison (!=) instead of numeric comparison (-ne) for
cpuset values like "0-1".
For example:
$ [[ "0-1" != "2-3" ]] && echo "true" || echo "false"
true
$ [[ "0-1" -ne "2-3" ]] && echo "true" || echo "false"
false
