    afs: Check UHasTokens in afs_GCUserData
    
    It looks that EndTimestamp holds the user’s token expiration time even after
    function afs_MarkUserExpired() gets called from afs_pag_destroy().  So it
    seems that the PAGs/tokens are not being reclaimed. This will lead to pag
    buildup on the system.
    
    The PAG/'struct unixuser' is not being freed because afs_GCUserData() checks
    afs_HasUsableTokens(), which checks EndTimestamp, which says the tokens still
    haven't expired. So the PAG doesn't get freed.
    
    This behavior has existed since commit ba1d050c6e (Make unixuser's vid
    advisory).
    
    To fix this, change afs_GCuserData() to check for the UHasTokens flag, and
    ignore any tokens if UHasTokens isn't set. This causes the PAG to be freed,
    since we don't look at the EndTimestamp of the tokens at all.
    
    Thanks Todd DeSantis for your support.
