[Intel-wired-lan] [net-next PATCH 03/15] bnx2x: Move all UDP port notifiers to single function

[Alexander Duyck <aduyck@mirantis.com>]

This patch goes through and combines the notifiers for VXLAN and GENEVE
into a single function for each action.  So there is now one combined
function for getting ports, one for adding the ports, and one for deleting
the ports.

While going through and updating this I also removed the use of IS_ENABLED
for the CONFIG_BNX2X_GENEVE checks and instead just checked for defined
since there is no option to have this as a module.
