The existing Geneve locking scheme was pulled over directly from VXLAN. However, VXLAN has a number of built in mechanisms which make the locking more complex and are unlikely to be necessary with Geneve. This simplifies the locking to use a basic scheme of a mutex when doing updates plus RCU on receive. In addition to making the code easier to read, this also avoids the possibility of a race when creating or destroying sockets since UDP sockets and the list of Geneve sockets are protected by different locks. After this change, the entire operation is atomic. Signed-off-by:
