wifi: iwlwifi: trans: remove iwl_trans_init

We needed it for setting up trans parameters that could change later in
the probe flow.
This is no longer true, now we know all the parameters before we allocate the
trans, so we can just send the right parameters to iwl_trans_alloc and have all
initializations done there.
