Revert "geneve: pull IP header before ECN decapsulation"

commit c02bd115b1d25931159f89c7d9bf47a30f5d4b41 upstream.

This reverts commit 4179b00c04d1 ("geneve: pull IP header before ECN decapsulation").

Eric says: "network header should have been pulled already before
hitting geneve_rx()". Let's revert the syzbot fix since it's causing
more harm than good, and revisit.
