Linux: cache bypass: remove warning print before panic

Linux: cache bypass: remove warning print before panic

This warning printf has some issues - it prints out pointers as
ints with %d (which causes warnings), and if the intention was
to print the referenced values, they wouldn't be set yet at that
point in the function.

Since the purpose is not clear and it has issues, just remove it.
