Merge #15435: rpc: Add missing #include

39e20fc Add missing #include. (Daniel Kraft)

Pull request description:

  bd0dbe8 introduced a dependency of `rpc/util.h` on `RPCErrorCode`, defined in `rpc/protocol.h`.  The latter file is only included from `rpc/util.cpp`, though.  This commit fixes the missing include, by moving the `#include` of `rpc/protocol.h` to `rpc/util.h`.
