[avrc] Fix SendPlayerSettingsChanged logging

Instead of such logs:
10-18 12:42:48.389767  2203  2203 I bt_stack: [INFO:avrcp_service.cc(570)] attribute=PlayerAttribute::REPEAT : value=PlayerRepeatValue::OFF
10-18 12:42:48.389767  2203  2203 I bt_stack: attribute=PlayerAttribute::SHUFFLE : value=PlayerShuffleValue::OFF
10-18 12:42:48.389767  2203  2203 I bt_stack:

print:
03-15 11:38:19.864  4673  4673 I bluetooth: packages/modules/Bluetooth/system/btif/avrcp/avrcp_service.cc:569 SendPlayerSettingsChanged: {attribute=PlayerAttribute::REPEAT : value=PlayerRepeatValue::OFF}, {attribute=PlayerAttribute::SHUFFLE : value=PlayerShuffleValue::OFF}

Also handle the case when attributes size does not match values size.

Test: None - log only
