drm/amd/display: fix handling of max_downscale_src_width fail check in SPL
[Why]
If max_downscale_src_width check fails, we exit early from
spl_calculate_scaler_params but dscl_prog_data is not fully
populated. If viewport is left at 0, it can cause crash in dml.
[How]
Call spl_set_dscl_prog_data before we exit early from
spl_calculate_scaler_params to populate dscl_prog_data
Populate taps in spl_get_optimal_number_of_taps
