[PATCH] Fix kernel BUG() with iptree IP set on 2.4

[Marcus Sundberg <marcus@ingate.com>]

Hi,

The slab cache in 2.4(.31) uses a fixed length array for slab cache
names, causing a BUG() in mm/slab.c:kmem_cache_create() to be
triggered when attempting to create a cache who's name is longer
than 18 characters. The patch below makes iptree work on 2.4 kernels
as well:
