While do PF reset with function i40e_reset_and_rebuild(), it will
call i40e_init_pf_fcoe() by default if FCOE is defined, thus if the
PF is resetted, FCOE will be enabled whatever it was - enabled or
not.
Such bug might be hit when PF resumes from suspend, run diagnostic
test with ethtool, setup VLAN etc.
Passed building with v3.19-rc3.
