This fixes commit 0107635e15ac
("staging: qlge: replace pr_err with netdev_err") which introduced an
build breakage with dumping enabled, i.e.,

    $ QL_ALL_DUMP=1 QL_OB_DUMP=1 QL_CB_DUMP=1 QL_REG_DUMP=1 \
      QL_IB_DUMP=1 QL_DEV_DUMP=1 make M=drivers/staging/qlge

Fixes: 0107635e15ac ("taging: qlge: replace pr_err with netdev_err")
			^ staging

Thank you for reminding me of the typo!

This can be fixed without adding another argument:

	struct tx_ring *tx_ring = container_of(wqicb, struct tx_ring, wqicb);
	struct ql_adapter *qdev = tx_ring->qdev;

 	netdev_err(qdev->ndev, "Dumping wqicb stuff...\n");

... similar comment for the other instances.

Thank you for the simpler solution!

For QL_OB_DUMP and QL_IB_DUMP, `struct ql_adapter *qdev` can't be
obtained via container_of. So qdev are still directly passed to these
functions.
