Steven Rostedt (Google) 25742aeb13 ring-buffer: Remove stale comment from ring_buffer_size() ...

It's been 11 years since the ring_buffer_size() function was updated to
use the nr_pages from the buffer->buffers[cpu] structure instead of using
the buffer->nr_pages that no longer exists.

The comment in the code is more of what a change log should have and is
pretty much useless for development. It's saying how things worked back in
2012 that bares no purpose on today's code. Remove it.
