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 ||
|             ^                                   ~~
