    vtpmmgr: Flush all transient keys
    
    We're only flushing 2 transients, but there are 3 handles.  Use <= to also
    flush the third handle since TRANSIENT_LAST is inclusive
    
    The number of transient handles/keys is hardware dependent, so this
    should query for the limit.  And assignment of handles is assumed to be
    sequential from the minimum.  That may not be guaranteed, but seems okay
    with my tpm2.
