    Btrfs: always store the mirror we read the eb from · 5cf1ab56

    A user reported a panic where we were trying to fix a bad mirror but the
    mirror number we were giving was 0, which is invalid.  This is because we
    don't do the transid verification until after the read, so as far as the
    read code is concerned the read was a success.  So instead store the mirror
    we read from so that if there is some failure post read we know which mirror
    to try next and which mirror needs to be fixed if we find a good copy of the
    block.  Thanks,
