qcacld-3.0: Code refine for SSDP and DTIM config

1) 'ssdp' in t_wma_handle structure is not used anymore,
   remove this redundant field.
2) ucfg_pmo_set_sta_mod_dtim and ucfg_pmo_get_sta_mod_dtim
   should have been accessing 'sta_mod_dtim' instead of
   'sta_dynamic_dtim' in struct pmo_psoc_cfg.
