net: phy: leds: Refactor "no link" handler into a separate function
Currently, phy_led_trigger_change_speed() is handling a "no link" condition like it was some kind of an error (using "goto" to a code at the function end). However, having no link at PHY is an ordinary operational state, so let's handle it in an appropriately named separate function so it is more obvious what the code is doing. Signed-off-by: Maciej S.
