io_uring: Fix probe of disabled operations
io_probe checks io_issue_def->not_supported, but we never really set
that field, as we mark non-supported functions through a specific ->prep
handler. This means we end up returning IO_URING_OP_SUPPORTED, even for
disabled operations. Fix it by just checking the prep handler itself.
