net: bcmgenet: don't set phydev->link from MAC

When commit 28b2e0d ("net: phy: remove parameter new_link from
phy_mac_interrupt()") removed the new_link parameter it set the
phydev->link state from the MAC before invoking phy_mac_interrupt().

However, once commit 88d6272 ("net: phy: avoid unneeded MDIO
reads in genphy_read_status") was added this initialization prevents
the proper determination of the connection parameters by the function
genphy_read_status().

This commit removes that initialization to restore the proper
functionality.

Fixes: 88d6272 ("net: phy: avoid unneeded MDIO reads in genphy_read_status")
