Lai Jiangshan da706d8bc8 ring_buffer: Fix warning while ignoring cmpxchg return value ...

kernel/trace/ring_buffer.c: In function 'rb_tail_page_update':
kernel/trace/ring_buffer.c:849: warning: value computed is not used
kernel/trace/ring_buffer.c:850: warning: value computed is not used

Add "(void)"s to fix this warning, because we don't need here to handle
the fail case of cmpxchg, it's fine if an interrupt already did the
job.

Changed from V1:
  Add a comment(which is written by Steven) for it.
