thunderbolt: Fix -Wrestrict warning
gcc-11 warns when building with W=1: drivers/thunderbolt/xdomain.c: In function 'modalias_show': drivers/thunderbolt/xdomain.c:733:16: error: 'sprintf' argument 3 overlaps destination object 'buf' [-Werror=restrict] 733 | return sprintf(buf, "%s\n", buf); | ^~~~~~~~~~~~~~~~~~~~~~~~~ drivers/thunderbolt/xdomain.c:727:36: note: destination object referenced by 'restrict'-qualified argument 1 was declared here 727 | char *buf) | ~~~~~~^~~ There is no need for the sprintf() here when a strcat() does the same thing.
