wireguard: converted whitespaces from space to tab
With this change, the file is reduced from 5186 bytes to 4649 bytes that its approximately 10.5 percent less memory consumption. For small devices, sometimes every byte counts. Also, all other protocol handler use tabs instead of spaces. Signed-off-by: Florian Eckert <fe@dev.tdt.de>
