Erorrs after amd blockchain driver update

**HI

I have a vega 56 and upgraded from the latest amd driver to the blockchain one. After the update with nothing changed in the config i just get this mess.

clinfo found only nvidia opencl. This means there are some pathes to amd opencl missing or the driver is not installed correctly.
