Jens Axboe e0ee967630 io_uring/kbuf: sanitize peek buffer setup ...

Harden the buffer peeking a bit, by adding a sanity check for it having
a valid size. Outside of that, arg->max_len is a size_t, though it's
only ever set to a 32-bit value (as it's governed by MAX_RW_COUNT).
Bump our needed check to a size_t so we know it fits. Finally, cap the
calculated needed iov value to the PEEK_MAX_IMPORT, which is the
maximum number of segments that should be peeked.

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