ata fix for 6.12-rc5

Browse Source 
- Fix the handling of ATA commands that timeout (command that did not
    receive a completion interrupt within the configured timeout time).
 
    Commands that timeout, while also having either the FAILFAST flag
    set, or the command being a passthrough command, should never be
    retried. Restore this behavior (as it was before v6.12-rc1).
