bna: fix skb->truesize underestimation
skb->truesize is not meant to be tracking amount of used bytes
in an skb, but amount of reserved/consumed bytes in memory.
For instance, if we use a single byte in last page fragment,
we have to account the full size of the fragment.
skb->truesize can be very different from skb->len, that has
a very specific safety purpose.
