    [IPSEC] esp: Remove NAT-T checksum invalidation for BEET
    I pointed this out back when this patch was first proposed but it looks like
    it got lost along the way.
    The checksum only needs to be ignored for NAT-T in transport mode where
    we lose the original inner addresses due to NAT.  With BEET the inner
    addresses will be intact so the checksum remains valid.
