radv: return binary code_size not variant code size to cache

The code sizes return here get passed to the cache shader insert function,
which then memcpy from the code ptr, and causes all sorts of valgrind
errors like:

Since we are just inserting the code into the cache, we can avoid these
bad reads and data in the cache by just using the binary code size here.
