[PATCH 1/2] add missing PACK_PTR_LIST()

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

At two places in the code, DELETE_PTR() is called on soem list
but PACK_PTR_LIST() is not called at the end of the loop.
This potentially leave empty ptrlist 'blocks' which are not handled
by the usual list walking macros.

No concrete situation have been found where a real problem
occurs but better be safe than sorry and call PACK_PTR_LIST()
here too.
