rfnoc: Fix transport buffer reservations
Change transports to reserve the number of frame buffers they actually
need from the I/O service. Previously some I/O service clients reserved
0 buffers since they shared frame buffers with other clients, as we know
the two clients do not use the links simultaneously. This is possible
with the inline_io_service but not with a multithreaded I/O service
which queues buffer for clients before they are requested.
