Alexander Motin b2565f51fc Do not sent 120 TEST UNIT READY requests on generic NOT READY statuses.
Some failing disks tend to return vendor-specific ASC/ASCQ codes with
NOT READY sense key.  It caused extremely long recovery attempts, repeating
these 120 TURs (it takes at least 1 minute) for every I/O request.
Instead of that use default error handling, doing just few retries.
