aio: don't bother with unmapping when aio_free_ring() is coming from exit_aio() ... since exit_mmap() is coming and it will munmap() everything anyway. In all other cases aio_free_ring() has ctx->mm == current->mm; moreover, all other callers of vm_munmap() have mm == current->mm, so this will allow us to get rid of mm argument of vm_munmap().
