2020-03-21hw/rdma: Skip data-path mr_id translationYuval Shaia
With the change made in commit 68b89aee71 ("Utilize ibv_reg_mr_iova for memory registration") the MR emulation is no longer needed in order to translate the guest addresses into host addresses. With that, the next obvious step is to skip entirely the processing in data-path. To accomplish this, return the backend's lkey to driver so we will not need to do the emulated mr_id to backend mr_id translation in data-path. The function build_host_sge_array is still called in data-path but only for backward computability with statistics collection. While there, as a cosmetic change to make the code cleaner - make one copy of the function rdma_backend_create_mr and leave the redundant guest_start argument in the legacy code.

2020-03-21hw/rdma: Cosmetic change - no need for two sge arraysYuval Shaia
The function build_host_sge_array uses two sge arrays, one for input and one for output. Since the size of the two arrays is the same, the function can write directly to the given source array (i.e. input/output argument).

2020-03-20compat: disable edid on correct virtio-gpu deviceCornelia Huck
Commit bb15791166c1 ("compat: disable edid on virtio-gpu base device") tried to disable 'edid' on the virtio-gpu base device. However, that device is not 'virtio-gpu', but 'virtio-gpu-device'. Fix it.

We were eliding all zero indexes. It is only ld==0 that does not have an index in the instruction. This also allows us to avoid breaking the final print into multiple pieces.
