[PATCH] eth: fbnic: Fix modpost undefined error

[Jinjie Ruan]

When CONFIG_FBNIC=m, the following error occurs:

	ERROR: modpost: "priv_to_devlink" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "page_pool_create" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "devlink_info_serial_number_put" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "page_pool_alloc_pages" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "devlink_priv" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "page_pool_put_unrefed_page" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "devlink_unregister" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "devlink_alloc_ns" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "devlink_register" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!
	ERROR: modpost: "devlink_free" [drivers/net/ethernet/meta/fbnic/fbnic.ko] undefined!

The driver now uses functions exported from a helper module
but fails to link when the helper is disabled, select them to fix them
