jfs_debug.h uses an incorrect CONFIG_KERNEL_ASSERT ifdef to redefine the
assert macro for kgdb use. I believe the code worked a long time ago, but
today it's not a valid config option. Since I'm not aware of anybody
interested in debugging jfs with kgdb, it should just be removed.
Thanks to Robert P. J. Day for reporting this.
