Subject: scsi: lpfc: Fix reported physical link speed on a disabled trunked
Git-commit: 845d0327bf0885e7d2fb6cb18e800491be793250
Patch-mainline: v5.4-rc1
References: bsc#1146215
 link

GetTrunkInfo is displaying an incorrect link speed when the link is a trunk
and the link has gone down.  The driver is not clearing the logical speed
as part of the link down transition.

Fix by setting the logical speed to UNKNOWN SPEED when the link goes down.
