mvd: bugfix in the coordinate transformation

A bugfix in the coordinate transformation of MVD hits.

fSensor->TopToPixel(local, indexX, indexY); is called with the array of size 2 (local[2]), while it assumes the size of 3:

https://git.cbm.gsi.de/se.gorbunov/cbmroot/-/blob/dev/core/detectors/mvd/CbmMvdSensor.cxx?ref_type=heads#L413

Because of this bug, MVD hits sometimes get bogus values in Z, for example X -0.0901254 Y -0.86012 Z 1.10751e+19

This MR should fix the problem of the hanging CA tracking in the other MR: !1557 (diffs)

In addition, I'll add an extra check of the input data in the CA tracking later.

Thanks for finding this. The top coordinate should obviously always be a valid x, y, z coordinate.
