Fix report on port offload capabilities to be 0 (no capabilities).
Before this commit port capabilities were a clone of queue
capabilities, however the current TAP offload capabilities (e.g.
checksum calculation) are per queue and are not specific per port.
Fixes: 95ae196ae10b ("net/tap: use new Rx offloads API")
Fixes: 818fe14a9891 ("net/tap: use new Tx offloads API")
