[patch] CacheFiles: delete unused code in cachefiles_cook_key()

[Dan Carpenter <dan.carpenter@oracle.com>]

This code was presumably left over from previuos unpublished versions.

We set "len" twice to 0 and then to 5 a couple lines below.  We set
"seg" to 250 or 252, then check if it is less than zero (it isn't) so
I have deleted all the "seg" related code.
