The set_offload() argument list is already pretty long and
we are going to introduce soon a bunch of additional offloads.
Replace the offload arguments with a single struct and update
all the relevant call-sites.
No functional changes intended.
Signed-off-by: Paolo Abeni <pab...@redhat.com>

Note: I maintained the struct usage as opposed to uint64_t bitmask usage
as suggested by Akihiko, because the latter feel a bit more invasive.
v1 -> v2:
- drop unneeded 'struct' keywords
- moved to series start
