qcacld-3.0: Kbuild: Cleanup DISA_OBJS logic

Currently DISA_OBJS are added to OBJS when CONFIG_WLAN_FEATURE_DISA is
enabled. An upcoming change requires that assignments to OBJS be
unconditional. Fortunately the assignment of .o files to DISA_OBJS is
already conditional upon CONFIG_WLAN_FEATURE_DISA so remove the
condition from the assignment to OBJS.
