[GIT PULL] cgroup fixes for v4.19-rc7

[Tejun Heo]

Hello, Greg.

One cgroup2 threaded mode fix for v4.19-rc7.  While threaded mode
isn't used widely (yet) and the bug requires somewhat convoluted
sequence of operations, it causes a userland visible malfunction -
EINVAL on a valid attempt to enable threaded mode.  This pull request
contains the fix.

Thanks.
