    net/iavf: fix scalar Rx path zero-length segment
    
    When hardware CRC stripping is active, a frame whose on-wire size is an
    exact multiple of the Rx buffer size can cause the NIC to fill the final
    data descriptor and place the four CRC bytes into a separate trailing
    descriptor. After hardware stripping, that descriptor carries zero bytes
    of payload.
    
    The existing CRC cleanup code only handles a zero-length trailing segment
    when software CRC stripping is enabled. When hardware stripping is
    active, the zero-length mbuf is silently chained to the reassembled
    packet. Forwarding such a packet causes a zero-length Tx descriptor,
    triggering a Malicious Driver Detection event on the PF and resetting
    the VF.
    
    Fix by adding logic to detect a zero-length final segment when hardware
    CRC stripping is active, and freeing it.
