RFR: 8217362: Emergency dump does not work when disk=false is set

[Yasumasa Suenaga]

Hi all,

Please review this change:

  JBS: https://bugs.openjdk.java.net/browse/JDK-8217362
  webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8217362/webrev.00/

We cannot get emergency dump of flight record if disk=false is passed
to HotSpot.
This change works fine on all tests on submit repo and jdk_jfr jtreg tests.


Thanks,

Yasumasa
