ixgbe: Drop unnecessary addition from ixgbe_set_rx_buffer_len

Browse Source 
We still had some code floating around from the old single buffer receive
path.  As a result we were adding VLAN_HLEN to max_frame although the
resultant value was never used.  Since that is the case we can drop this from
the function.
