v2.x : Segmentation fault in Aint tests with IB

[sjeaugey]

Aint tests have been broken for a long time in v2.x (~ at the same time we got all the onesided tests failing also).

The onesided fixes on openib fixed all errors on master, but on v2.x, there are still tests failing : aint and c_post_start. Not sure it c_post_start is the same error as I can't get a working core file, but the stack for aint is :

Tracked it down to the two missing commits. Once open-mpi/ompi-release#1009 is in 2.x we can close this.
