iwlwifi: MAC_ACCESS_REQ cleanup

Add txq_id info to "Tx queue requesting wakeup" debug message

Add "Rx queue requesting wakeup" debug message

Move clear of CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ to be after nearby
iwl_write_prph(), since iwl_write_prph() sets it and clears it.  Almost
removed it entirely, but just making sure in case someone removes the
iwl_write_prph()!  Also remove unneeded priv->lock usage; this is now
handled by priv->reg_lock within iwl_clear_bit().

Join a couple of lines that had unneeded line returns.
