iwlwifi: allocated rx page accounting cleanup
In iwlwifi, priv->alloc_rxb_page is used to keep track of the Rx pages allocated by the driver. This cleans up the page free routines by introducing __iwl_free_pages/iwl_free_pages so that the accounting is more accurate and less error prone. This also fixes two instances where the counter was not updated. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
