Modified Files:
        src/sys/kern: vfs_cache.c

Log Message:
vfs_cache - do not write outside allocated memory.

In cache_cpu_init allocate struct nchcpu, not struct nchstats_percpu.
cache_update_stats expects the former (that contains two percpu
structs).  Stat updates where smashing whatever was in the next pool
allocation.

Reported by martin@ as crashes in ptyfs on Krups.
