[PATCH] Replace IS_ENABLED(CONFIG_FCOE) in linux/netdevice.h

On platforms that (or configs that do not have PCI support building any
code that includes linux/netdevice.h we see the following warnings:

include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE" is not defined [-Wundef]
include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef]

In the case of this file we can trivially fallback to the old school
 #if defined(...) syntax.

On platforms that (or configs that do not have PCI support building any
code that includes linux/netdevice.h we see the following warnings:

include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE" is not defined [-Wundef]
include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef]

In the case of this file we can trivially fallback to the old school
 #if defined(...) syntax.

Fix IS_ENABLED to handle cases like this so we don't need special
cases like this scattered around the tree.

The script that generates those symbols should be fixed instead.

Sorry all, Yes this patch is bogus.

The platform was seeing this error wasn't sourceing
drivers/scsi/Kconfig, so those symbols will never be defined.  I imagine
that's pretty rare.
