io_uring/cmd: drop unused res2 param from io_uring_cmd_done() 

Commit 79525b51ac ("io_uring: fix nvme's 32b cqes on mixed cq") split
out a separate io_uring_cmd_done32() helper for ->uring_cmd()
implementations that return 32-byte CQEs. The res2 value passed to
io_uring_cmd_done() is now unused because __io_uring_cmd_done() ignores
it when is_cqe32 is passed as false. So drop the parameter from
io_uring_cmd_done() to simplify the callers and clarify that it's not
possible to return an extra value beyond the 32-bit CQE result.
