net: phy: remove parameter new_link from phy_mac_interrupt()
I see two issues with parameter new_link:
1. It's not needed. See also phy_interrupt(), works w/o this parameter.
phy_mac_interrupt sets the state to PHY_CHANGELINK and triggers the
state machine which then calls phy_read_status. And phy_read_status
updates the link state.
2. phy_mac_interrupt is used in interrupt context and getting the link
state may sleep (at least when having to access the PHY registers
via MDIO bus).
So let's remove it.
