From: Vitaly Kuznetsov <vkuzn...@redhat.com>
The only user of scsi_prep_async_scan() is scsi_scan_host() and it handles
the situation correctly. Move 'called twice' reporting to debug level as
well.
The issue is observed on Hyper-V: on any device add/remove event storvsc
driver calls scsi_scan_host() and in case previous scan is still running
we get the message and stack dump on console.
