bpf_map_create usage question

[Grant Seltzer Richman <grantseltzer@xxxxxxxxx>]

Hi there,

If I call `bpf_map_create()` successfully I'll have a file descriptor
and not a `struct bpf_map`. This stifles me from using a lot of the
`bpf_map__` API functions, for example `bpf_map__pin()`. What's the
reason for this? Is there a way to get a  `struct bpf_map` that I'm
missing?

Thanks so much,
Grant Seltzer

P.s. been a while since I've worked on adding docs, but I will finally
be getting back to it!
