mlxsw: spectrum: Remove pointless call to devlink_param_driverinit_value_set()

The "acl_region_rehash_interval" devlink parameter is a "runtime"
parameter, making the call to devl_param_driverinit_value_set()
pointless. Before cited commit the function simply returned an error
(that was not checked), but now it emits a WARNING [1].

Fix by removing the function call.
