nfsd: Properly compare and initialize kuids and kgids
Use uid_eq(uid, GLOBAL_ROOT_UID) instead of !uid. Use gid_eq(gid, GLOBAL_ROOT_GID) instead of !gid. Use uid_eq(uid, INVALID_UID) instead of uid == -1 Use gid_eq(uid, INVALID_GID) instead of gid == -1 Use uid = GLOBAL_ROOT_UID instead of uid = 0; Use gid = GLOBAL_ROOT_GID instead of gid = 0; Use !uid_eq(uid1, uid2) instead of uid1 != uid2. Use !gid_eq(gid1, gid2) instead of gid1 != gid2. Use uid_eq(uid1, uid2) instead of uid1 == uid2. Cc: "J.
