usb gadget ether: Fix warning in is_eth_addr_valid()

Browse source 
The gadget ethernet driver needs to keep copies of the MAC address (at
both endpoints) as strings so it needs a custom function for validation
of the MAC.  It was not however performing a totally correct check and
also was emitting a warning about a set but unused variable.  The
solution to both is that after checking the string contents we use the
standard test for a valid MAC.
