memcg, oom: remove unnecessary check in mem_cgroup_oom_synchronize()
mem_cgroup_oom_synchronize() is only used when the memcg oom handling is
handed over to the edge of the #PF path. Since commit 29ef680ae7c2
("memcg, oom: move out_of_memory back to the charge path") this is the
case only when the kernel memcg oom killer is disabled
(current->memcg_in_oom is only set if memcg->oom_kill_disable). Therefore
a check for oom_kill_disable in mem_cgroup_oom_synchronize() is not
required.
