[PATCH 4.14 33/53] net/qla3xxx: fix an error code in ql_adapter_up()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Dan Carpenter <dan.carpenter@oracle.com>

commit d17b9737c2bc09b4ac6caf469826e5a7ce3ffab7 upstream.

The ql_wait_for_drvr_lock() fails and returns false, then this
function should return an error code instead of returning success.

The other problem is that the success path prints an error message
netdev_err(ndev, "Releasing driver lock\n");  Delete that and
re-order the code a little to make it more clear.
