Use ILLEGAL_MODE macro to silence clang error.

This fixes the following clang error:

../../tests/XfermodeTest.cpp:43:44: error: comparison of constant -1 with expression of type 'SkXfermode::Mode' is always false [-Werror,-Wtautological-constant-out-of-range-compare]
    REPORTER_ASSERT(reporter, reportedMode == -1);
