Alexander Motin 20507534d4 OpenZFS 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.
