RDMA/mana_ib: Fix a bug when the PF indicates more entries for registering memory on first packet

When registering memory in a large chunk that doesn't fit into a single PF
message, the PF may return GDMA_STATUS_MORE_ENTRIES on the first message if
there are more messages needed for registering more chunks.

Fix the VF to make it process the correct return code.
