proresdec_lgpl: explicitly check coff[3] against slice_data_size
The implicit checks via v_data_size and a_data_size don't work in the case
'(hdr_size > 7) && !ctx->alpha_info'.
This fixes segmentation faults due to invalid reads.
This problem was introduced in commit
547c2f002a87f4412a83c23b0d60364be5e7ce58.
