RFR (T) 8237217: Incorrect G1StringDedupEntry type used in StringDedupTable destructor

[Aleksey Shipilev]

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8237217

Spotted this when reading the strdedup code. This is a trivial leftover from JDK-8203641.
G1StringDedupEntry symbol does not even exist, and the whole thing works because FREE_C_HEAP_ARRAY
ignores that parameter. But it should be consistent anyway with constructor anyway.

I would not bother with jdk-submit testing, as it looks pretty trivial.

Fix:

diff -r f7edb9ca045c src/hotspot/share/gc/shared/stringdedup/stringDedupTable.cpp
