cku 319d409383 Bug 1424922 - Prevent calling PDFiumParent::Close twice. r=dvander ...

We call PDFiumParent::Close twice under certain conditions. Once in
PDFiumProcessParent::Delete, and once in PDFiumProcessParent's dtor. So we may
hit MOZ_ABORT which tell us that we are trying to close a closed channel.

This patch prevents hitting this abort by:
1. Only close the channel in PDFiumProcessParent::Delete, remove another call
   in PDFiumProcessParent's dtor. (Please see the change in
   PDFiumProcessParent.cpp).
2. Remove PDFiumParent::AbortConversion and relative code. We can just use
   PDFiumParent::EndConversion instead. When calling PDFiumParent::Close, we
   actually close the IPC channel *synchronously*, which means there is no need
   to register a callback by PDFiumParent::AbortConversion to receive
   actor-destroy callback.
