lmkd: fix the cgroup attribute name to MemCgroupEventControl 

which was CgroupEventControl before, but it's not the one
that definied in system/core/libprocessgroup/profiles/task_profiles.json.

And it causes lmkd crash for some setups like 4.19q + AOSP Master

Bug: 230642311

Test: boot the 4.19q + AOSP master setup with hikey960 board
