[PATCH] mtd-utils: Disable LZO compression by default

When the recent LZO compression support went into mtd-utils recently,
it was enabled by default.  This means that mkfs.jffs2 will default to
creating images with lzo compression as the default.

Older kernels cannot decompress such images, so lzo should be disabled
by default.  The patch below fixes this.  To enable lzo compression
from now on, simply pass '-X lzo' as an option to mkfs.jffs2.
