ring_buffer: fix ring_buffer_read_page()
Impact: change API and init bpage when copy
ring_buffer_read_page()/rb_remove_entries() may be called for
a partially consumed page.
Add a parameter for rb_remove_entries() and make it update
cpu_buffer->entries correctly for partially consumed pages.
ring_buffer_read_page() now returns the offset to the next event.
Init the bpage's time_stamp when return value is 0.
