Ref.impl. v2. Store max perms as well, ensure that the
channel will not get more privileges on restore than it had
at creation time.

Ref.impl. V1. Simple escalation. Allows the VFS to shoot
itself in the foot by opening a channel R only, getting it W
in close, and trying to write, failing, maybe crashing.
Tomorrow we will extend that to keep max and effective perms
around.
