    sbin/hammer: Fix/remove redundant error variable
    
    Check ioctl result right after ioctl.
    Since this for-loop expects ioctl(GET_PSEUDOFS) to eventually
    return ENOENT for a new slot, error variable is likely to be
    overwritten with ENOENT by the time for-loop ends. This could
    result in overlooking possible real errors.
    
    If errno is checked (if not ENOENT) right after ioctl, there's
    also no need to preserve errno value.
