====================
wireguard fixes for 5.7-rc4

This series contains two fixes and a cleanup for wireguard:

1) Removal of a spurious newline, from Sultan Alsawaf.

2) Fix for a memory leak in an error path, in which memory allocated
   prior to the error wasn't freed, reported by Sultan Alsawaf.

3) Fix to ECN support to use RFC6040 properly like all the other tunnel
   drivers, from Toke Høiland-Jørgensen.
