perf symbols: Check if a struct machine instance was found

Which can happen when processing old files that had no fake kernel MMAP,
events.

That shouldn't result in perf_session__create_kernel_maps not being
called, this will be fixed in a followup patch, for now do these checks
to avoid segfaulting.
