  1. wd: Fix GCC 12 build issue 

    Build errors happen with GCC 12

wd.c: In function 'wd_is_isolate':
wd.c:193:21: error: the comparison will always evaluate as 'true' for the address of 'dev_root' will never be NULL [-Werror=address]
  193 |         if (!dev || !dev->dev_root)
        |                     ^
	In file included from wd.c:21:
	./include/wd.h:131:14: note: 'dev_root' declared here
	  131 |         char dev_root[PATH_STR_SIZE];
	        |              ^~~~~~~~
		cc1: all warnings being treated as errors
		make[1]: *** [Makefile:816: wd.lo] Error 1

Fix by using strlen(dev->dev_root).
