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.
