    vol: Avoid getting stuck in ATTACHING in attach2
    
    Since commit 5fc2365f, a VNOVOL error early in attach2 meant that we
    skipped changing the volume state to anything, and just returned
    instead. When we do this, the volume is in VOL_STATE_ATTACHING for
    DAFS, and so if we return, the volume will forever be in
    VOL_STATE_ATTACHING. The next thing that tries to access the volume
    will wait forever for the volume to come out of that state.
    
    So, revert half of 5fc2365f, and transition to ERROR state instead.
    This code path should not be hit during normal usage, since a
    nonexistant volume access for the fileserver will be detected earlier.
    If the volume does not appear to exist at this stage of attachment,
    something is wrong with the volume, so this warrants the ERROR state.
    
    For the volserver and other volume utilities, we may hit this when a
    request just plain references a nonexistant volume for whatever
    reason, but in that case the vp should go away soon. For non-DAFS,
    this commit does not change much, since the difference between
    error_notbroken and unlocked_error is very small.
    
    The other half of 5fc2365f is not changed, since it is correct. For
    VOFFLINE errors at this point, the volume has already been
    transitioned to VOL_STATE_UNATTACHED, so it is okay to return. Add a
    comment to help make this more explicit.
