Source: ucx

Usertags: loong64

Dear maintainers,

Compiling the ucx failed for loong64 in the Debian Package Auto-Building 
environment.
The error log is as follows,
```
......
sys/iovec.c: In function 'ucs_iov_copy':
sys/iovec.c:47:13: error: too many arguments to function 
'ucs_memcpy_relaxed'
    47 |             ucs_memcpy_relaxed(iov_buf, 
UCS_PTR_BYTE_OFFSET(buf, copied), len,
       |             ^~~~~~~~~~~~~~~~~~
.......
```
The full build log can be found at 
https://buildd.debian.org/status/fetch.php?pkg=ucx&arch=loong64&ver=1.18.1%2Bds-1&stamp=1741101442&raw=0.

Please consider the patch I attached.
According to the function calling in ./src/ucs/sys/iovec.c file, I need 
to update the parameters of function ucs_memcpy_relaxed();.
Based on attached patch, I have built ucx (1.18.1+ds-1+loong64) 
successfully on locally.
```

```

Your opinions are welcome.

Best regards,
