usb: hcd: Bump local buffer size in rh_string()

GCC is not happy about the buffer size:

drivers/usb/core/hcd.c:441:48: error: ‘%s’ directive output may be truncated writing up to 64 bytes into a region of size between 35 and 99 [-Werror=format-truncation=]
  441 |                 snprintf (buf, sizeof buf, "%s %s %s", init_utsname()->sysname,
      |                                                ^~
  442 |                         init_utsname()->release, hcd->driver->description);
      |                         ~~~~~~~~~~~~~~~~~~~~~~~

Bump the size to get it enough for the possible strings.
