[PATCH 4/7] perf mmap: Using stored 'overwrite' in perf_mmap__consume

[kan.liang@linux.intel.com]

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

The 'overwrite' is set at initialization. It will not be changed.
Using it to replace the parameter of perf_mmap__consume().
The parameters will be discarded later.

No functional change.
