perf test: Report failure for mmap events
When fail to mmap events in task exit case, it misses to set 'err' to
-1; thus the testing will not report failure for it.
This patch sets 'err' to -1 when fails to mmap events, thus Perf tool
can report correct result.
Fixes: d723a55096b8 ("perf test: Add test case for checking number of EXIT
events")
