    kernel - Zero out syncache_percpu properly
    
    * The kmalloc for the syncache_percpu was not using M_ZERO
      which I believe can cause cache_count to be some random
      value.  If this value is close to or larger than the syncache
      limit, the garbage collector may run with no entries to reuse,
      causing a NULL pointer dereference and panic.
