Fixed 7058036: FieldsAllocationStyle=2 does not work in 32-bit VM

ClassFileParser::parseClassFile() incorrectly uses nonstatic_oop_map_size() 
method instead of nonstatic_oop_map_count() when calculates a pointer to last 
oop map block.

Verified by fields layout based on the example in the bug report.
