tracing/ring-buffer: remove unused ring_buffer size
Impact: remove dead code struct ring_buffer.size is not set after ring_buffer is initialized or resized. it is always 0. we can use "buffer->pages * PAGE_SIZE" to get ring_buffer's size Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
