From: Matthias Hintzmann <matthias.dev@xxxxxx>
ctx->drvflags is checked in the if clause before beeing initialized. Move initialization before first usage.
Note, that the if clause was backported from mainline at Nov. 15th 2017 (GetNtbFormat endian fix). In mainline, the initialization is at the right place before the if clause.
