Subject: [PATCH] Pass NULL instead of InvalidOid for pointer argument

MetaTrackAddUpdInternal() takes a HeapTuple as argument, which in
turn is defined as a pointer to a HeapTupleData structure. Pass
NULL rather than InvalidOid as that gets treated as a null pointer
constant causing a compiler warning:

heap.c:750:13: warning: expression which evaluates to zero treated
               as a null pointer constant of type 'HeapTuple'
               (aka 'struct HeapTupleData *')
      [-Wnon-literal-null-conversion]
