commit c75f7cda9b017cadcfcbc5f14637ab08aa2ae748
Author: Sangmin Seo <sseo at anl.gov>

    Do not reference a CH3 variable in ROMIO glue.
    Although MPIDI_CH3I_progress_blocked is a variable only used in CH3,
    it was referenced in the ROMIO glue code. This caused a build problem
    when pamid is used as a device. This patch removed the reference to
    MPIDI_CH3I_progress_blocked, but it degrades the efficiency of
    MPIR_Ext_cs_yield_allfunc_if_progress_blocked() since we do not have
    a way to check if the progress engine is blocked for now (related to
    ticket #2202). For a better solution for ticket #2202, we need to
    fix a wait function of the extended generalized request.
    Fixes #2242
