Log Message:
ixg(4): Don't print wrong error message about ixgbe_num_queues.

 Don't override the ixgbe_num_queues global variable. It's the default
value of the number of queues and should not override it because it
will be referenced by later device attach. For example, the number of
MSI-X vector is 64 on X540 and 18 on 82599. When both cards are inserted
to a machine that the number of CPU is 24 and X540 is probed earlier,
ixgbe_num_queues is overridden to 24 and the following error message is
printed when attaching 82599:

        ixg2: autoconfiguration error: ixgbe_num_queues (24) is too large,
        using reduced amount (17).

Note that the number of queues is in sc->num_queuss and referenced
by hw.ixgN.num_queues sysctl.
