pds_core: protect devlink callbacks from fw_down state
Don't access structs that have been cleared when in the fw_down
state and the various structs have been cleaned and are waiting
to recover. This caused a panic on rmmod when already in fw_down
and devlink_param_unregister() tried to check the parameters.
