EFA incorrectly implements FI_DELIVERY_COMPLETE in earlier libfabric
versions. While FI_DELIVERY_COMPLETE would be advertised by the
provider, completions would return too early by not accounting for
bounce buffers on the receive side. This would cause the BTL
to receive early completions that lead to correctness issues.
This is not an issue in the mtl/ofi as it does not require
FI_DELIVERY_COMPLETE.
