[pve-devel] [PATCH storage] Add check to overrule krbd setting on RBD storage

[Alwin Antreich]

The scfg variable holds an extra parameter to verify that it's lxc that
needs krbd regardless its storage config entry.

Without this there would be the need for an extra storage entry to use
the same RBD pool with LXC (krbd 0/1).
