udp: Validate checksum in udp_read_sock()
[ Upstream commit 099f896f498a2b26d84f4ddae039b2c542c18b48 ]
It turns out the skb's in sock receive queue could have bad checksums, as
both ->poll() and ->recvmsg() validate checksums. We have to do the same
for ->read_sock() path too before they are redirected in sockmap.
Fixes: d7f571188ecf ("udp: Implement ->read_sock() for sockmap")
