[pve-devel] [PATCH container v3 6/8] api: create: get rid of $storage_only_mode variable

[Fiona Ebner]

The name is rather vague. The variable is set if and only if there are
no mp params specified via the API, so explicitly check for that
instead. This also makes it visible that in the non-restore case, the
result of create_ct_determine_mp_param() does not depend upon
$api_mp_param.
