Title: Fix iallgather problem with intercommunicators

A problem was found with the libnbc MPI_Iallgather
routine when using intercommunicators. Special
thanks to Takahiro Kawashima(Fujitsu) for the patch
and a test case. Verified master fails without the
patch and the test passes with the patch applied.
