devlink: fix the name of value arg of devl_param_driverinit_value_get()

Probably due to copy-paste error, the name of the arg is "init_val"
which is misleading, as the pointer is used to point to struct where to
store the current value. Rename it to "val" and change the arg comment
a bit on the way.
