devlink: make sure driver does not read updated driverinit param before reload
The driverinit param purpose is to serve the driver during init/reload
time to provide a value, either default or set by user.
Make sure that driver does not read value updated by user before the
reload is performed. Hold the new value in a separate struct and switch
it during reload.
Note that this is required to be eventually possible to call
devl_param_driverinit_value_get() without holding instance lock.
