Log:
  9434 Speculative prefetch is blocked by device removal code.
  
  Device removal code does not set spa_indirect_vdevs_loaded for pools
  that never experienced device removal.  At least one visual consequence
  of it is completely blocked speculative prefetcher.  This patch sets
  the variable in such situations.
