r600/sfn: Fix test compilation with -fno-rtti

79ca456b4837b3bc21cf9ef3c03c505c4b4909f6 reintroduced the use
of dynamic_cast<> in r600/sfn tests.  This breaks compilation with
-fno-rtti, as required to build against the LLVM configuration
recommended upstream.  Use static_cast<> instead to fix this.

Fixes: #7820
