Al Viro 561e3a0c40 io_uring/fdinfo: fix io_uring_show_fdinfo() misuse of ->d_iname ...

Output of io_uring_show_fdinfo() has several problems:

* racy use of ->d_iname
* junk if the name is long - in that case it's not stored in ->d_iname
at all
* lack of quoting (names can contain newlines, etc. - or be equal to "<none>",
for that matter).
* lines for empty slots are pointless noise - we already have the total
amount, so having just the non-empty ones would carry the same information.
