net: selectively purge error queue in IP_RECVERR / IPV6_RECVERR
Setting IP_RECVERR and IPV6_RECVERR options to zero currently purges the socket error queue, which was probably not expected for zerocopy and tx_timestamp users. I discovered this issue while preparing commit 6b5f43ea0815 ("inet: move inet->recverr to inet->inet_flags"), I presume this change does not need to be backported to stable kernels. Add skb_errqueue_purge() helper to purge error messages only.
