perf test: Report failure for mmap events


[ Upstream commit 6add129c ]

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: d723a550 ("perf test: Add test case for checking number of EXIT events")
