Originally "fd" was unsigned int but it was changed to int when we pulled
this code into a separate function in commit 0b6d253e084a
("io_uring/register: provide helper to get io_ring_ctx from 'fd'"). This
doesn't really cause a runtime problem because the call to
array_index_nospec() will clamp negative fds to 0 and nothing else uses
the negative values.
