Fix strncmp(...) length when looking for "edges"

Any tree contain edge data would fail to read. As the
strncmp(...) to look for "edges" was passing a length
of 4, this would also match "edge_data"! Use a length
of 5 instead.

BUG #14202. Modify arrays when changed.

vtkMFIXReader was not modifying reused arrays when the contents were changed.
That was causing ParaView to report incorrect array bounds. Fixed that.
