Gabriel Krisman Bertazi 7703ee4c86 io_uring: Fix probe of disabled operations 
[ Upstream commit 3e05b222382ec67dce7358d50b6006e91d028d8b ]

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.

Fixes: 66f4af93da57 ("io_uring: add support for probing opcodes")
