Rename NetinfoRequestHandler::is_block_relay data member to is_tx_relay
Rename NetinfoRequestHandler::is_block_relay data member to is_tx_relay

and inverse its logic.

The naming is out of date and incorrect, as lack of request of tx relay does not
imply block relay, and a preference for tx relay doesn't imply that block relay
isn't happening.
