rdm_sr_eager_auto fails intermittently

[sungeunchoi]

This test has comment in it that says a sleep(1) should enable auto progress to do it's thing. I don't think this is good enough.

[RUN ] rdm_sr_eager_auto::senddata_eager_auto
[----] prov/gni/test/rdm_sr.c:1260: Assertion failed: The expression (ret) == (2) is false.
