test_cls_rbd: avoid warning -Wno-unnamed-template-args

According to this https://code.google.com/p/googletest/source/detail?r=446
the use of unnamed types (in this case the protection flag enums from
librbd/parent_types.h) as template parameters (in this case the gtest
macros) is not valid C++ pre C++0x.

As suggested, converting the enum into an int with integral promotion
via unary plus operator solves the problem.
