ocfs2: add extra flags check in ocfs2_ioctl_move_extents()
In 'ocfs2_ioctl_move_extents()', add extra check whether only actually
supported flags are passed via 'ioctl(..., OCFS2_IOC_MOVE_EXT, ...)',
and reject anything beyond OCFS2_MOVE_EXT_FL_AUTO_DEFRAG and
OCFS2_MOVE_EXT_FL_PART_DEFRAG with -EINVAL. In particular,
OCFS2_MOVE_EXT_FL_COMPLETE may be set by the kernel only and
should never be passed from userspace.
