[gparted] Check LVM cache only for LVM physical volumes

[Curtis Gedak <gedakc src gnome org>]

commit 50befd62a321aaac8ae85778ba05f31216e7e696
Author: Rogier Goossens <goossens rogier gmail com>

    Check LVM cache only for LVM physical volumes
    
    Determine the FS type before checking whether a FS is busy,
    and check LVM only for LVM PVs.
    
    Remove the LVM busy check for extended partitions, as they
    don't contain LVM PVs - or any other FS for that matter.
    (and even if they did, the rest of the code silently assumes
    they don't...)
