[PATCH 4.13 13/27] selftests: timers: Fix run_destructive_tests target to handle skipped tests

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Shuah Khan <shuahkh@osg.samsung.com>

commit df9c011c0a23cf1399c01f896cd359d932ab49b5 upstream.

When a test exits with skip exit code of 4, "make run_destructive_tests"
halts testing. Fix run_destructive_tests target to handle error exit codes.
