Change the type of the res2 parameter in io_uring_cmd_done from ssize_t to u64. This aligns the parameter type with io_req_set_cqe32_extra, which expects u64 arguments. The change eliminates potential issues on 32-bit architectures where ssize_t might be 32-bit. Only user of passing res2 is drivers/nvme/host/ioctl.c and it actually passes u64.
