nfp: only clean sp_indiff when application firmware is unloaded

Browse Source 
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.

Fixes: b1e4f11e426d ("nfp: refine the ABI of getting `sp_indiff` info")
