io_uring: fix buffer auto-commit for multishot uring_cmd
Commit 620a50c92700 ("io_uring: uring_cmd: add multishot support") added
multishot uring_cmd support with explicit buffer upfront commit via
io_uring_mshot_cmd_post_cqe(). However, the buffer selection path in
io_ring_buffer_select() was auto-committing buffers for non-pollable files,
which conflicts with uring_cmd's explicit upfront commit model.
This way consumes the whole selected buffer immediately, and causes
failure on the following buffer selection.
Fix this by checking uring_cmd to identify operations that handle buffer
commit explicitly, and skip auto-commit for these operations.
