When initializing XDP in virtnet_open(), some rq xdp initialization may hit an error causing net device open failed. However, previous rqs have already initialized XDP and enabled NAPI, which is not the expected behavior. Need to roll back the previous rq initialization to avoid leaks in error unwinding of init code. Also extract a helper function of disable queue pairs, and use newly introduced

is_power_of_2() already performs the zero check. Hence avoid duplicate check. While at it, move the query of size check also adjacent to where its used for the disabled vq.
