[PATCH] fix a warning on kernel/trace/trace_branch.c

[Zhenwen Xu <helight.xu@gmail.com>]

fix this warning:

kernel/trace/trace_branch.c: In function ‘probe_likely_condition’:
kernel/trace/trace_branch.c:58: warning: passing argument 1 of ‘
trace_buffer_lock_reserve’ from incompatible pointer type

The "tr" should be "(struct buffer *)tr" or "tr->buffer" here!!!
