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.

Fixes: 6ba48ff46f76 ("x86: Remove arbitrary instruction size limit in instruction decoder")
