[ Upstream commit ad35ffa252af67d4cc7c744b9377a2b577748e3f ]

Change curr_link_speed advertised speed, due to
link_info.link_speed is not equal phy.curr_user_speed_req.
Without this patch it is impossible to set advertised
speed to same as link_speed.

Testing Hints: Try to set advertised speed
to 25G only with 25G default link (use ethtool -s 0x80000000)

Fixes: 48cb27f2fd18 ("ice: Implement handlers for ethtool PHY/link operations")
