RFR: 8255005: Fix indentation levels in classFileParser.cpp

[Harold Seigel]

Please review this very small change to fix indentation in classFileParser.cpp and move the check for the PermittedSubclasses attribute inside of the "if (major_version >= 16)" block.

Fix was tested with tiers 1 and 2 on Linux, Mac OSX, and Windows, and tiers 3-5 on Linux x64.

Thanks, Harold
