This commit removes the unnecessary call to `fi_getinfo()` when
initializing the MTL. `cq_data_size` is a domain attribute that will be
available to the MTL from the initial query itself. FI_DIRECTED_RECV is
a primary capability that has to be requested for a provider to enable
it, so adding that to the initial requirement. The redundant query was
also overwriting the contents of the prov object, which already had the
include/exclude filtering and multi-NIC logic applied to it.
