    The constant MPIDI_TAG_UB is used in only one place at the moment, in the
    initialization of ch3 (source:src/mpid/ch3/src/mpid_init.c@4b35902a#L131). The
    problem is that the value which is being set (MPIR_Process.attrs.tag_ub) is
    set differently in pamid (INT_MAX). This leads to weird results when we set
    apart a bit in the tag space for failure propagation in non-blocking
    collectives (see #2008).
    
    Since this value isn't being referenced anywhere else, there doesn't seem to
    be a use for it and it's just leading to confusion. To avoid this, here we
    remove this value and just set MPIR_Process.attrs.tag_ub to INT_MAX in both
    ch3 and pamid.
