crypt: fix evaluation of args to macro

GCC 7 warns about the following

crypt.c:3685:31: warning: ?: using integer constants in boolean context,
the expression will always evaluate to ‘true’ [-Wint-in-bool-context]
        local->op_ret < 0 ? -1 : 0,
../../../../libglusterfs/src/stack.h:342:36: note: in definition of
macro ‘STACK_UNWIND_STRICT’
                         } else if (op_ret == 0) {
\
                                    ^~~~~~
}

This is because args to pre-processor are lazily evaluated and operator
precedence for == is higher than ?:
