From: Kunwu Chan <chentao@kylinos.cn>

Increase size of the servername array to avoid truncated output warning.

net/sunrpc/clnt.c:582:75: error：‘%s’ directive output may be truncated
writing up to 107 bytes into a region of size 48
[-Werror=format-truncation=]
582 | snprintf(servername, sizeof(servername), "%s",
| ^~

net/sunrpc/clnt.c:582:33: note:‘snprintf’ output
between 1 and 108 bytes into a destination of size 48
582 | snprintf(servername, sizeof(servername), "%s",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
583 | sun->sun_path);
