seg6: fix skb checksum in SRv6 End.B6 and End.B6.Encaps behaviors
[ Upstream commit f048880fc77058d864aff5c674af7918b30f312a ]
The SRv6 End.B6 and End.B6.Encaps behaviors rely on functions
seg6_do_srh_{encap,inline}() to, respectively: i) encapsulate the
packet within an outer IPv6 header with the specified Segment Routing
Header (SRH); ii) insert the specified SRH directly after the IPv6
header of the packet.
This patch removes the initialization of the IPv6 header payload length
from the input_action_end_b6{_encap}() functions, as it is now handled
properly by seg6_do_srh_{encap,inline}() to avoid corruption of the skb
checksum.
Fixes: 140f04c33bbc ("ipv6: sr: implement several seg6local actions")
