s390/qeth: drop redundant state checking
Now that qeth always uses dev_close() to shutdown the interface, we can trust the locking and remove some custom state checks. qeth_l?_stop_card() is no longer called for a card in UP state, so remove the checks there too. This basically makes the UP state obsolete, so rip out the whole thing (except for the sysfs-visible string). Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
