Sishuai Gong 5310760af1 ipvs: fix racy memcpy in proc_do_sync_threshold
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.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
