Some of the sessions tests in the ompi-tests/ibm test suite fail when using the UCX PML.

These weren't previously observed because only recently was this PML made sessions aware.

Another case where the MCA system gets shut down if no more "instances" are present,
but unless --enable-mca-dso is used, the UCX common has retained info about memory
allocation, etc. that is no longer correct.
