wpaul 00f007fade Fix some memory bugs with regard to jumbo buffers. I made a mistake when
converting from the old external mbuf buffer code to the new (with the
MEXTADD() macro). Also free free list memory correctly in
foo_free_jumbo_mem() routines: grab the head of the list, then
remove it, _then_ free() it.

This fixes the memory corruption problem I've been chasing in the level 1
driver.
