Adrian Hunter 20aa39708a perf intel-pt: Fix premature IPC 
The code assumed a change in cycle count means accurate IPC. That is not
correct, for example when sampling both branches and instructions, or at
a FUP packet (which is not CYC-eligible) address. Fix by using an explicit
flag to indicate when IPC can be sampled.

Fixes: 5b1dc0fd1d ("perf intel-pt: Add support for samples to contain IPC ratio")
