Christoph Hellwig cf68d334dd scsi: push host_lock down into scsi_{host,target}_queue_ready 
Prepare for not taking a host-wide lock in the dispatch path by pushing
the lock down into the places that actually need it.  Note that this
patch is just a preparation step, as it will actually increase lock
roundtrips and thus decrease performance on its own.
