[IPSEC]: Move ip_summed zapping out of xfrm6_rcv_spi
Not every transform needs to zap ip_summed. For example, a pure tunnel
mode encapsulation does not affect the hardware checksum at all. In fact,
every algorithm (that needs this) other than AH6 already does its own
ip_summed zapping.
This patch moves the zapping into AH6 which is in line with what IPv4 does.
Possible future optimisation: Checksum the data as we copy them in IPComp.
