ice: fix 200G link speed message log

Commit 24407a01 ("ice: Add 200G speed/phy type use") added support
for 200G PHY speeds, but did not include 200G link speed message
support. As a result the driver incorrectly reports Unknown for 200G
link speed.

Fix this by adding 200G support to ice_print_link_msg().
