[nft PATCH RFC v2 1/4] mnl: Consolidate mnl_batch_talk() parameters

[Phil Sutter <phil@nwl.cc>]

The single caller of this function passes struct netlink_ctx fields as
the first two parameters. This can be simplified by passing the context
object itself and having mnl_batch_talk() access it's fields instead.
