staging/lustre: Remove now obsolete memory tracking sysctls
In the past when Lustre did its own allocation amounts tracking the results were shown in sysctl as current and overall max number of bytes and pages allocated. Now that we don't track these, remove the sysctls. Signed-off-by: Oleg Drokin <green@linuxhacker.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
