Fix mismatched deallocation functions

In fe_memutils.h, we have various allocation functions beginning with
either pg_ or p. The pg_ functions have a matching pg_free() for
freeing memory, while the p functions use pfree(). In some cases, we
were allocating memory with one set of functions while using the wrong
deallocation functions. This creates a tiny bit of mental overhead
when reading code. Matching up allocation and deallocation functions
makes it easier to analyze memory handling in a code path.
