[IP]: Simplify and consolidate MSG_PEEK error handling
When a packet is obtained from skb_recv_datagram with MSG_PEEK enabled
it is left on the socket receive queue. This means that when we detect
a checksum error we have to be careful when trying to free the packet
as someone could have dequeued it in the time being.
Currently this delicate logic is duplicated three times between UDPv4,
UDPv6 and RAWv6. This patch moves them into a one place and simplifies
the code somewhat.
This is based on a suggestion by Eric Dumazet.
