Andreas Rheinhardt ca04589371 avcodec/cbs_h2645: Fix potential out-of-bounds array access ...

The maximum allowed index for an array access is FF_ARRAY_ELEMS - 1; yet
the current code allowed FF_ARRAY_ELEMS. This wasn't dangerous in practice,
as parameter sets with invalid ids were already filtered out during
reading.

Found via PVS-Studio (see ticket #8156).
