Details:

When mdnsResponder responses a query, it sends wrong protocol strings back,
'p' character is missing.

This is because in few cases the mdns_domain_add_label() function is called
with wrong length value.

The error caused by taking sizeof() a pointer instead of desired string, e.g.:
(u8_t)(sizeof(dnssd_protos[DNSSD_PROTO_UDP])-1).

This results in missing character of 'p' from "_tcp" and "_udp" strings.
