[PATCH] ring-buffer: Fix bytes_dropped calculation issue

[Feng Yang]

From: Feng Yang <yangf...@kylinos.cn>

The calculation of bytes-dropped and bytes_dropped_nested is reversed.
Although it does not affect the final calculation of total_dropped,
it should still be modified.

Fixes: 6c43e554a2a5 ("ring-buffer: Add ring buffer startup selftest")
