Maciej Fijalkowski 6ae1d209c6 xdp: reflect tail increase for MEM_TYPE_XSK_BUFF_POOL
[ Upstream commit fbadd83a612c3b7aad2987893faca6bd24aaebb3 ]

XSK ZC Rx path calculates the size of data that will be posted to XSK Rx
queue via subtracting xdp_buff::data_end from xdp_buff::data.

In bpf_xdp_frags_increase_tail(), when underlying memory type of
xdp_rxq_info is MEM_TYPE_XSK_BUFF_POOL, add offset to data_end in tail
fragment, so that later on user space will be able to take into account
the amount of bytes added by XDP program.
