Subject: [PATCH bpf-next v2 05/11] bpf: offload: rename bpf_offload_dev_match() to bpf_offload_prog_map_match()

A set of new API functions exported for the drivers will soon use
'bpf_offload_dev_' as a prefix.  Rename the bpf_offload_dev_match()
which is internal to the core (used by the verifier) to avoid any
confusion.
