Modernize geom_stats_snapshot_get

* A logically useless memset() is used to fault in some memory pages.
  Change it to explicit_bzero so the compiler won't eliminate it.

* Eliminate the second memset.  It made sense in the days of the Big
  Kernel Lock, but not in the days of fine-grained SMP and especially
  not in the days of VDSO.
