Typo in view.cpp::void wsrep::view::print it should be protocol instead of prococol

[ShahriyarR]

Replace prococol with protocol:

void wsrep::view::print(std::ostream& os) const
{
    os << "  id: " << state_id() << "\n"
       << "  status: " << to_c_string(status()) << "\n"
       << "  prococol_version: " << protocol_version() << "\n"
       << "  capabilities: " << provider::capability::str(capabilities())<<"\n"
       << "  final: " << (final() ? "yes" : "no") << "\n"
       << "  own_index: " << own_index() << "\n"
       << "  members(" << members().size() << "):\n";

    for (std::vector<wsrep::view::member>::const_iterator i(members().begin());
         i != members().end(); ++i)
    {
        os << "\t" << (i - members().begin()) /* ordinal index */
           << ": " << i->id()
           << ", " << i->name() << "\n";
    }
}
