Alex HungandGreg Kroah-Hartman 1726914cb1 drm/amd/display: Skip wbscl_set_scaler_filter if filter is null 
[ Upstream commit c4d31653c0 ]

Callers can pass null in filter (i.e. from returned from the function
wbscl_get_filter_coeffs_16p) and a null check is added to ensure that is
not the case.

This fixes 4 NULL_RETURNS issues reported by Coverity.
