Peter Zijlstra 0f363b250b x86: Fix off-by-one in instruction decoder 
Stephane reported that the PEBS fixup was broken by the recent commit to
the instruction decoder. The thing had an off-by-one which resulted in
not being able to decode the last instruction and always bail.

Reported-by: Stephane Eranian <eranian@google.com>
Fixes: 6ba48ff46f ("x86: Remove arbitrary instruction size limit in instruction decoder")
