i40e: move I40E_FLAG_UDP_FILTER_SYNC to the state field
This flag is modified during run time, possibly even when the RTNL lock
is not held. Additionally it has a few places which should be using
test_and_set or test_and_clear atomic bit operations.
Create a new state bit __I40E_UDP_SYNC_PENDING and use it instead of the
ole I40E_FLAG_UDP_FILTER_SYNC flag.
This is part of a larger effort to remove the need for using cmpxchg64
in i40e_set_priv_flags.
