rpc: fix deadlock when unref is inside conn->lock

In ping-timer implementation, the timer event takes a ref on the rpc
object. This ref needs to be removed after every timeout event.
ping-timer mechanism could be holding the last ref. For e.g, when a peer
is detached and its rpc object was unref'd. In this case, ping-timer
mechanism would try to acquire conn->mutex to perform the 'last' unref
while being inside the critical section already. This will result in a
deadlock.
