[PATCH 002 of 4] Make the initial RPC PING interruptible.

[NeilBrown <neilb@suse.de>]

If an RPC client is created with CREATE_INTR and not CREATE_NOPING,
then the ping should be interruptible.  With tcp the PING can take 30
seconds to time out and not being able to interrupt that can be
frustrating.
