Currently, 'PVE::Storage::DirPlugin' is implicitly passed along as
$class, which means that if the base class's free_image calls another
method (e.g. filesystem_path) then the DirPlugin's method will be
used, rather than the one from BTRFSPlugin. Change it so that $class
itself is passed along.
See also commit 279d9de510 for context,
where the approach in this patch was suggested.
