net: zynq_gem: Do not return -ENOSYS on success
The .read_rom_hwaddr net_ops hook does not check the return value, which
is why it was never caught that we are currently returning 0 if the
read_rom_hwaddr function return -ENOSYS and -ENOSYS otherwise.
In this case we can simplify this by just returning the result of the
function.
