This was newly introduced and is only used once, so having a wantarray return mechanism, without ever using it or knowing for sure if this may help with reuse of the method is not ideal. Make the sub a module private one just returning the vm disk number or explicit undef. Pass it the $suffix variable, to avoid recomputing it every time called by out caller's loop. If there's re-use potential in the future we can actually decide what makes sense to return. Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
