The method is only derived in the DirPlugin module from the base
Plugin, so we do not have it available there through a static module
method call using ::, but only when using a class dereference.
Other fix options would have been:
PVE::Storage::Plugin::free_image(@_);
or:
$class->SUPER::free_image($storeid, ...);
