rpc: silence coverity warning

Coverity noted that 4 out of 5 calls to virNetClientStreamRaiseError
checked the return value.  This case expects a particular value, so
warn if our expectations went wrong due to some bug elsewhere.

* src/rpc/virnetclient.c (virNetClientCallDispatchStream): Warn on
  unexpected scenario.
