vti4: eliminated some duplicate code.

commit f981c57ffd2d7cf2dd4b6d6f8fcb3965df42f54c upstream.

The ipip tunnel introduced in commit dd9ee3444014 ("vti4: Fix a ipip
packet processing bug in 'IPCOMP' virtual tunnel") largely duplicated
the existing vti_input and vti_recv functions.  Refactored to
deduplicate the common code.
