    Commit 18a4d0a2
    (Handle disk devices which can not process medium access commands)
    was introduced to offline any device which cannot process medium
    access commands.
    However, commit 3eef6257
    (Reduce error recovery time by reducing use of TURs) reduced
    the number of TURs by sending it only on the first failing
    command, which might or might not be a medium access command.
    So in combination this results in an erratic device offlining
    during EH; if the command where the TUR was sent upon happens
    to be a medium access command the device will be set offline,
    if not everything proceeds as normal.
    
    This patch moves the check to the final test, eliminating
    this problem.
