RDMA/irdma: Report the correct link speed

[ Upstream commit 4eace75e0853273755b878ffa9cce6de84df975a ]

The active link speed is currently hard-coded in irdma_query_port due
to which the port rate in ibstatus does reflect the active link speed.

Call ib_get_eth_speed in irdma_query_port to get the active link speed.
