Fix GCOV build errors for AXONE configuration

This commit fixes two problems that were preventing GCOV
instrumentation from building:

1. There was an uninitialized variable in fapi2GetChildrenTest.H
2. The PNOR layout for AXONE had physical offsets for each partition
   specified manually, which was thwarting the automatic offset
   calculation required to be able to successfully adjust the partition
   layout when the size of HBI exceeds its initial allotment due to
   GCOV instrumentation

There is another uninitialized-variable warning in the import tree
which will be fixed by another commit.
