Andreas Rheinhardt f25caec87f avformat/mxfdec: Fix memleak upon repeating tags 
When parsing MXF encountering some tags leads to allocations. And when
these tags were encountered repeatedly, this could lead to memleaks,
because the pointer to the old data got simply overwritten with a
pointer to the new data (or to NULL on allocation failure). This has
been fixed.
