Some commands like turning local Tx/Rx pause on/off do not need link
to go down. If there are issues with link config params, then the
firmware will explicitly indicate link down in reply. So, don't always
link down for every link config param change request. Instead, rely
on actual link status coming in firmware's link config change reply.

Fixes: 61570952b138 ("net/cxgbe: rework and simplify link handling code")
