wireguard: add burst mode

Originally wireguard does packet by packet encryption and decryption. This patch adds burst mode for encryption and decryption packets. In addition, it contains some performance improvement such as prefetching packet header and reducing the number of current time function calls. Type: improvement Signed-off-by: Gabriel Oginski <gabrielx.oginski@intel.com> Change-Id: I04c7daa9b6dc56cd15c789661a64ec642b35aa3f
