ibmvnic: skip send_request_unmap for timeout reset
[ Upstream commit 7d3a7b9ea59ddb223aec59b45fa1713c633aaed4 ]
Timeout reset will trigger the VIOS to unmap it automatically,
similarly as FAILVOER and MOBILITY events. If we unmap it
in the linux side, we will see errors like
"30000003: Error 4 in REQUEST_UNMAP_RSP".
So, don't call send_request_unmap for timeout reset.
