Since the introduction of the on-demand proc allocation
the check become erroneous and irrelevant.
Moreover, it completely breaks OpenSHMEM support in OMPI.

@shamisp This breaks with UCX, right? I think we determined earlier today that it doesn't break OSHMEM with MXM because MXM disables on-demand addprocs (which is why we hadn't seen this before).

@hppritcha We discussed this earlier today. If this passes CI (it might still run into the RDMACM problem at Mellanox Jenkins), I think we should merge so that we can get an MTT night in with it.

I don't have MXM to try but I suspect it does. It breaks yoda for sure. I have not seen any special disable code in OSHMEM code. I only saw the code in the OMPI codebase which is not shared with OSHMEM.

I"m good with merging this. I'm still confused as to how the mlnx jenkins oshmem tests were working though.
