percona_status_wait_query_cache_mutex test does not restore the pre-test state

[Laurynas Biveinis]

This is probably introduced by the fix to bug 878709. It looks like DEBUG_SYNC state is not properly reset at the end of the testcase.

http://jenkins.percona.com/job/percona-server-5.1-param/219/BUILD_TYPE=debug,Host=centos6-64/console:

main.percona_status_wait_query_cache_mutex w3 [ pass ] 7

MTR's internal check of the test case 'main.percona_status_wait_query_cache_mutex' failed.
This means that the test case does not preserve the state that existed
before the test case was executed. Most likely the test case did not
do a proper clean-up. It could also be caused by the previous test run
by this thread, if the server wasn't restarted.
This is the diff of the states of the servers before and after the
test case was executed:
