net: qcom/emac: disable interrupts before calling phy_disconnect
There is a race condition that can occur if EMAC interrupts are
enabled when phy_disconnect() is called. phy_disconnect() sets
adjust_link to NULL. When an interrupt occurs, the ISR might
call phy_mac_interrupt(), which wakes up the workqueue function
phy_state_machine(). This function might reference adjust_link,
thereby causing a null pointer exception.
