git-bisect agrees with this as well.

I initially thought it was because GlusterD didn't listen on IPv6
(checked using `ss`).
This change makes it so that connections to localhost use ::1 instead
of 127.0.0.1, and so the connection failed.
This should have caused all connection attempts to fail, irrespective
of it being encrypted or not.
But the failure only happens when management encryption is enabled.
So this theory doesn't make sense.

One other thing was on my laptop, even bricks failed to start when
glusterd was started with management encryption.
But on a VM, the bricks started, but other daemons failed.
