[PATCH net-next 2/2] net: rose: Escape trigraph to fix warning with W=1

[Andrew Lunn]

net/rose/af_rose.c: In function ‘rose_info_show’:
net/rose/af_rose.c:1413:20: warning: trigraph ??- ignored, use -trigraphs to 
enable [-Wtrigraphs]
 1413 |    callsign = "??????-?";

??- is a trigraph, and should be replaced by a ˜ by the
compiler. However, trigraphs are being ignored in the build. Fix the
warning by escaping the ?? prefix of a trigraph.
