nfp: only clean `sp_indiff` when application firmware is unloaded
Currently `sp_indiff` is cleaned when driver is removed. This will cause problem in multi-PF/multi-host case, considering one PF is removed while another is still in use. Since `sp_indiff` is the application firmware property, it should only be cleaned when the firmware is unloaded. Now let management firmware to clean it when necessary, driver only set it.
