Sishuai Gong 6650bebaa5 ipvs: fix racy memcpy in proc_do_sync_threshold ...

[ Upstream commit 5310760af1 ]

When two threads run proc_do_sync_threshold() in parallel,
data races could happen between the two memcpy():

Thread-1			Thread-2
memcpy(val, valp, sizeof(val));
				memcpy(valp, val, sizeof(val));

This race might mess up the (struct ctl_table *) table->data,
so we add a mutex lock to serialize them.
