hv_netvsc: Fix IP header checksum for coalesced packets
[ Upstream commit bf48648d650db1146b75b9bd358502431e86cf4f ]
Incoming packets may have IP header checksum verified by the host.
They may not have IP header checksum computed after coalescing.
This patch re-compute the checksum when necessary, otherwise the
packets may be dropped, because Linux network stack always checks it.
