of_net: fix of_get_mac_address retval if compiled without CONFIG_OF 

of_get_mac_address prior to commit d01f449c00 ("of_net: add NVMEM
support to of_get_mac_address") could return only valid pointer or NULL,
after this change it could return only valid pointer or ERR_PTR encoded
error value, but I've forget to change the return value of
of_get_mac_address in case where the kernel is compiled without
CONFIG_OF, so I'm doing so now.
