net: phy: fixed_phy: Fix fixed_phy not checking GPIO

[ Upstream commit 8f289805616e81f7c1690931aa8a586c76f4fa88 ]

Fix fixed_phy not checking GPIO if no link_update callback
is registered.

In the original version all users registered a link_update
callback so the issue was masked.

Fixes: a5597008dbc2 ("phy: fixed_phy: Add gpio to determine link up/down.")
