net/i40e: fix max frame size config at port level

net/i40e: fix max frame size config at port level

Previously, max frame size can only be set when link is up, and the wait
time is 1 sec. Startup time of 10G_BASET longer than 1s would result in
failure.

Actually, max frame size of media type I40E_MEDIA_TYPE_BASET can be set
regardless of link status.

This patch omitted the link status check of 10G_MEDIA_TYPE_BASET.
