geneve: fix an uninitialized value in geneve_changelink()
[ Upstream commit 32818c075c54bb0cae44dd6f7ab00b01c52b8372 ]
geneve_nl2info() sets 'df' conditionally, so we have to
initialize it by copying the value from existing geneve
device in geneve_changelink().
Fixes: 56c09de347e4 ("geneve: allow changing DF behavior after creation")
