iwlwifi: remove alive start adhoc restart

This code will never trigger, because when
we call this during interface start, neither
priv->vif nor priv->iw_mode conditions will
be true, and when it happens during reset
then priv->vif is also NULL. Also, in both
cases the same code will be executed as part
of iwl_bss_info_changed(), which contains a
copy of this code.
