FPII-2399 : Elevation of privilege vulnerability in kernel networking
subsystem (device specific) CVE-2016-7117 A-30515201

There is a potential use-after-free vulnerability when the underlying recvmsg calls
return some packets and then hit an error, which will make recvmmsg set sock->sk->sk_err.
The fix is designed to prevent the setting of sock->sk->sk_err after an error,
preventing the potential use-after-free vulnerability.
