RFR 8229930: internal_name() in annotations.hpp returns "{constant pool}"

[Harold Seigel]

Hi,

Please review this trivial fix to correct a misspelling and a probable 
cut-and-paste error.

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8229930

The fix was regression tested by running Mach5 tiers 1 and 2 tests and 
builds on Linux-x64, Solaris, Windows, and Mac OS X and by running JCK 
lang and VM tests on Linux-x64.

Thanks, Harold
