[net-2.6 PATCH] ixgbe: fix for real_num_tx_queues update issue

[Jeff Kirsher]

From: Vasu Dev <vasu.dev@intel.com>

Currently netdev_features_change is called before fcoe tx queues
setup is done, so this patch moves calling of netdev_features_change
after tx queues setup is done in ixgbe_init_interrupt_scheme, so
that real_num_tx_queues is updated correctly on each fcoe enable
or disable.

This allows additional fcoe queues updated correctly in vlan driver
for their correct queue selection.
