Subject: scsi: lpfc: Fix reported physical link speed on a disabled trunked
 link
Patch-mainline: v5.4-rc1
Git-commit: 845d0327bf0885e7d2fb6cb18e800491be793250
References: jsc#SLE-8284 jsc#SLE-8654

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.
