drm/imagination: Fixed warning due to implicit cast to bool
This line appears to confuse the compiler and had been noticed previously in
clang-tidy output. There isn't anything fundamentally wrong that I can see.
I suspect that it just looks like a mistake - hence the first note. By making
the second operand an actual bool result, const correctness can be preserved
while silencing the warning.
