accounting bh->b_count in page->count

accounting bh->b_count in page->count

[Alexey Zhuravlev]

Hello!

why do not change bh->b_page->count on getblk/brelse?
this could prevent situation when a page that can't be
freed by try_to_free_buffers from buffercache lives on
inactive_dirty list and VM try to free it every time...

We have to watch out for one thing though ... we have
to be able to write inactive_dirty pages to disk without
having them move back to the active list ;)
