usbnet: add a mutex around phy register access
When working on the mcs7830, I noticed the need for a mutex in its
mdio_read/mdio_write functions. A related problem seems to be present
in the asix driver in the respective functions.
This introduces a mutex in the common usbnet driver and uses it
from the two hardware specific drivers.
