[IPVS]: Fix sched registration race when checking for name collision.
The register_ip_vs_scheduler() checks for the scheduler with the same name under the read-locked __ip_vs_sched_lock, then drops, takes it for writing and puts the scheduler in list. This is racy, since we can have a race window between the lock being re-locked for writing. The fix is to search the scheduler with the given name right under the write-locked __ip_vs_sched_lock.
