8210307: 8210246 broke NMT jtreg tests

[Thomas Stüfe]

Hi all,

may I please have reviews for this tiny and trivial fix:

cr: http://cr.openjdk.java.net/~stuefe/webrevs/8210307-8210246-broke-NMT-jtreg-tests/webrev.00/webrev/
Bug: https://bugs.openjdk.java.net/browse/JDK-8210307

8210246 macrofied (don't know a better name :) the memory types, which
is fine, but added additional quotes, which changes NMT output and
breaks all tests.

Fix is very simple. Just remove the additional quotes, which reverts
NMT output to what it was before.

Thank you,

Thomas
