Quentin 25/10/2021: bugfix RESTART reproductibility. In the case of no online chemistry (LORILAM=F) or LDUST/LSALT=T processes changing the aerosols (XAER)
at each time-step, XAER is computed once at the START segment in ini_ecmwf_radiations based on current pressure and not updated during MESONH except if LAERO_FT=T and CAER='TEGE'. At RESTART, the aerosols climatology is updated but the
pressure has changed. For reproductibility, one must use LAERO_FT=T and CAER='TEGE'. XAER_CLIM was not updated in the process done by CALL AEROZON in phys_param
