by benjamin.andrew.stephensRemoving "if" statement around calculation of wp4 in pdf_closure_module.F90 and the same "if" statement around some further manipulation of wp4 in advance_clubb_core. Results are bit-for-bit with this change, since normally all cases calculate wp4 anyway since the "if" condition was always satisfied in normal runs (but not, for example, in some tuning runs). This was done because the new wp3_pr_dfsn term needs wp4 in its current formulation so it needs to always be calculated.
See #920.
