Subject: [PATCH v1 14/19] DynamicTablesPkg: PPTT: Fix uninitialized memory usage
On enabling the /analyse option the VS2017 compiler
reports: warning C6001: Using uninitialized memory.
This warning is reported as some variables that were
being logged were uninitialised. To fix this, moved
the logging code after the variables being logged are
initialised.
