Jens Axboe f274495aea io_uring/kbuf: return correct iovec count from classic buffer peek 
io_provided_buffers_select() returns 0 to indicate success, but it should
be returning 1 to indicate that 1 vec was mapped. This causes peeking
to fail with classic provided buffers, and while that's not a use case
that anyone should use, it should still work correctly.

The end result is that no buffer will be selected, and hence a completion
with '0' as the result will be posted, without a buffer attached.

Fixes: 35c8711c8f ("io_uring/kbuf: add helpers for getting/peeking multiple buffers")
