i40e: move I40E_FLAG_TEMP_LINK_POLLING to state field
This flag is modified outside of the RTNL lock and thus should not be
part of the pf->flags variable.
Use a state bit instead, so that we can use atomic bit operations.
This is part of a larger effort to remove cmpxchg64 in
i40e_set_priv_flags()
