Remove PrintBufferDescs() and PrintPinnedBufs().

Browse Source 
These have been #ifdef'd out for a long time, and in fact have
been uncompilable since commit 48354581a of 2016-04-10.  The
fact that nobody noticed for so long demonstrates their lack of
usefulness, so let's remove them rather than fix them.
