On some platforms ACPI method `\\_SB.AMAC` is dynamic and changes to it can
influence changing the behavior of MAC pass through and what MAC address is used.

When running USB reset, re-read the MAC address to use to support tools that
change the policy.

This is quite similar to using `SIOCSIFHWADDR` except that the actual MAC to use
comes from ASL rather than from userspace.

Changes from v1:
 * Remove an extra unneeded `ether_addr_copy` call
 * Use `dev_set_mac_address` to ensure all notifiers are called
 * Shuffle functions to allow code re-use.

Mario Limonciello (2):
  r8152: remove extra action copying ethernet address
  r8152: Refresh MAC address during USBDEVFS_RESET
