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.
