Similar to AF_XDP, do not allow queues in a physical netdev to be resized by ethtool -L when they are leased. Cover channel resize paths (both netlink and ioctl) to reject resizing when the queues would be affected. Given we need to have different checks for RX vs TX, detangle the code into a two-loop version rather than the range of new_combined + min(new_rx, new_tx) to old_combined + max(old_rx, old_tx).
