Kan Liang 53172f9057 perf kvm: Switch to new perf_mmap__read_event() interface 
The perf kvm still use the legacy interface.

Switch to the new perf_mmap__read_event() interface for perf kvm.

No functional change.

Committer notes:

Tested before and after running:

  # perf kvm stat record

On a machine with a kvm guest, then used:

  # perf kvm stat report

Before/after results match and look like:

  # perf kvm stat record -a sleep 5
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 2.132 MB perf.data.guest (1828 samples) ]
  # perf kvm stat report
