Prefixed cmake WITH_ definitions with WSREP_LIB_ to avoid collisions

with superproject definitions.

Avoid using client_service::do_2pc() in before_commit() to
determine if 2pc is actually happening, will use transaction
states to deduce that. client_service::do_2pc() should be deprecated.

Fixed a compiler warning in db_high_priority_service.cpp.
