    debugfs: introduce stub for debugfs_create_size_t() when DEBUG_FS=n

    Toralf FÃ¶rster <toralf.foerster@....de> reported a build failure in
    the WiMAX stack when CONFIG_DEBUG_FS=n

    http://linuxwimax.org/pipermail/wimax/2009-January/000449.html

    This is due to debugfs_create_size_t() missing an stub that returns
    -ENODEV when the DEBUGFS subsystem is not configured in (like the rest
    of the debugfs API).

    This patch adds said stub.
