It could be xmit type was not set and would default to FLOW_OFFLOAD_XMIT_NEIGH
and in this type the gc expect to have a route info.
Fix that by adding FLOW_OFFLOAD_XMIT_UNSPEC which defaults to 0.

Fixes: 8b9229d15877 ("netfilter: flowtable: dst_check() from garbage collector path")

Notes:
    v2
    - add FLOW_OFFLOAD_XMIT_UNSPEC instead of still using neigh as default and checking dst for null
