memcg: fix wrong check of noswap with softlimit
Hierarchical reclaim doesn't swap out if memsw and resource limits are thye same (memsw_is_minimum == true) because we would hit mem+swap limit anyway (during hard limit reclaim). If it comes to the soft limit we shouldn't consider memsw_is_minimum at all because it doesn't make much sense. Either the soft limit is bellow the hard limit and then we cannot hit mem+swap limit or the direct reclaim takes a precedence.
