Normally all of the buffers will have been forced out to disk before we call invalidate_bdev(), but there will be some cases, where a file system operation was aborted due to an ext4_error(), where there may still be some dirty buffers in the buffer cache for the device. So try to force them out to memory before calling invalidate_bdev().
