net: recvmmsg: Strip MSG_WAITFORONE when calling recvmsg
recvmmsg fails on a raw socket with EINVAL. The reason for this is
packet_recvmsg checks the incoming flags:
err = -EINVAL;
if (flags & ~(MSG_PEEK|MSG_DONTWAIT|MSG_TRUNC|MSG_CMSG_COMPAT|MSG_ERRQUEUE))
goto out;
This patch strips out MSG_WAITFORONE when calling recvmmsg which
fixes the issue.
