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.
