Subject: [PATCH 4.19 384/639] RDMA/qedr: Fix incorrect device rate.

From: Sagiv Ozeri <sagiv.ozeri@...vell.com>

[ Upstream commit 69054666df0a9b4e8331319f98b6b9a88bc3fcc4 ]

Use the correct enum value introduced in commit 12113a35ada6 ("IB/core:
Add HDR speed enum") Prior to this change a 50Gbps port would show 40Gbps.

This patch also cleaned up the redundant redefiniton of ib speeds for
qedr.

Fixes: 12113a35ada6 ("IB/core: Add HDR speed enum")
