drm/amdgpu: Fix bounds checking in amdgpu_ras_is_supported()
The "block" variable can be set by the user through debugfs, so it can
be quite large which leads to shift wrapping here. This means we report
a "block" as supported when it's not, and that leads to array overflows
later on.
This bug is not really a security issue in real life, because debugfs is
generally root only.
