Jens Axboe bfc0aa7a51 io_uring/rsrc: add reference count to struct io_mapped_ubuf 
Currently there's a single ring owner of a mapped buffer, and hence the
reference count will always be 1 when it's torn down and freed. However,
in preparation for being able to link io_mapped_ubuf to different spots,
add a reference count to manage the lifetime of it.
