Very few places where a change is required, but remove FX_NEW to show
they've been audited.

The flag variable is conditionally initialized but unconditionally read.
Warning was:
src\fpdfapi\fpdf_page\fpdf_page_pattern.cpp(274) : warning C6001:

CPDF_Pattern objects are counted and maintained in m_PatternedMap.
When a CPDF_Pattern object "pattern" is deleted, it's address is marked as NULL in m_PatternMap.
This patch stores the address of CPDF_Pattern's adderss in all objects that references "pattern",
to ensure valid referencing after deletion.

This will prevent using freed pattern object.
This is a better solution than https://pdfium.googlesource.com/pdfium/+/1b9c5c4dc41956b8c5ab17b9a882adf8a2513768
and in essence revert that patch

Patterns are managed in CPDF_DocPageData. When
a document is closed, all patterns will be
released in the deconstruction of CPDF_DocPageData.
However, some patterns which are referenced in
CPDF_Color can't get the notification from the
destroy of CPDF_DocPageData. It will cause
use-after-free in CPDF_Color::~CPDF_Color.
