igb: Drop BUILD_BUG_ON check from igb_build_rx_buffer
On s390 the igb driver was throwing a build error due to the fact that a frame built using build_skb would be larger than 2K. Since this is not likely to change at any point in the future we are better off just dropping the check since we already had a check in igb_set_rx_buffer_len that will just disable the usage of build_skb anyway.
