i40e: Protect access to VF control methods
A scenario has been found in which simultaneous
addition/removal and modification of VF's might cause
unstable behaviour, up to and including kernel panics.
Protect the methods that create/modify/destroy VF's
by locking them behind an atomically set bit in PF status
bitfield.
