libsubcmd: Move va_end() before exit

This patch makes a minor adjustment by moving the va_end call before
exit. Since the exit() function terminates the program, any code
after exit(128) (i.e., va_end(params)) is unreachable and thus not
executed. Placing va_end before exit ensures that the va_list is
properly cleaned up.
