    LinuxKPI: correct the LINUXKPI_VERSION check for abs_diff()
    
    The code introduced abs_diff() as migrated from drm to standard
    linux headers.  The LINUXKPI_VERSION check did not allow this to
    be visible by default in-tree.  Make sure the v6.6 check is optional.
    drm-kmod always defines LINUXKPI_VERSION so this should be fine.
