[PATCH 2/7] perf mmap: Using the stored scope data in perf_mmap__push

[kan . liang]

From: Kan Liang <kan.li...@linux.intel.com>

Using the 'start' and 'end' which are stored in struct perf_mmap to
replace the temporary 'start' and 'end'.
The temporary variables will be discarded later.

No functional change.
