ALSA: hda - Add missing initial vmaster hook at build_controls callback
commit b63eae0a6c84839275a4638a7baa391be965cd0e upstream. The generic parser has a support of vmaster hook, but this is initialized only in the init callback with the check of the presence of the corresponding kctl. However, since kctl is NULL at the very first init callback that is called before build_controls callback, the vmaster hook sync is skipped there. Eventually this leads to the uninitialized state depending on the hook implementation. This patch adds a simple workaround, just calling the sync function explicitly at build_controls callback.
