Subject: [PATCH] mountd: Check for return of stat function
simplify the check, stat() return 0 on success -1 on failure
Fixes clang reported errors e.g.
| v4clients.c:29:6: error: logical not is only applied to the left hand side of this comparison [-Werror,-Wlogical-not-parentheses]
| if (!stat("/proc/fs/nfsd/clients", &sb) == 0 ||
| ^ ~~
