Call io_find_buf_node() to avoid duplicating it in io_nop().
IORING_NOP_FIXED_BUFFER interface looks odd, instead of pretending
to use a buffer, it basically pokes directly into internal infra,
it's not something userspace should be able to do.
Jens, did use it anywhere? It's new, I'd rather kill it or align with
how requests consume buffers, i.e. addr+len, and then do
io_import_reg_buf() instead. That'd break the api though, but would
anyone care?
3rd option is to ignore the flag and let the req succeed.
