[ Upstream commit a33395ab85 ]
If an rxrpc call is given a poke, it will get woken up unconditionally,
even if there's already a poke pending (for which there will have been a
wake) or if the call refcount has gone to 0.
Fix this by only waking the call if it is still referenced and if it
doesn't already have a poke pending.
Fixes: 15f661dc95 ("rxrpc: Implement a mechanism to send an event notification to a call")
