Sorry it appears there were two issues that we needed to resolve. The
first was the issue found with a randonconfig build where if the i40e
was compiled into the kernel and configfs was module, which this was
trying to correct.
The checks in the driver need to be changed from CONFIG_CONFIGFS_FS to
checking for CONFIG_I40E_CONFIGFS_FS, now that there is a Kconfig
option.
