io_work: convert shift argument to uintptr_t

io_work: convert shift argument to uintptr_t

Instead of passing the shift argument as pointer, pass
directly its integer value. This will allow the code to
distinguish a shift value from a real object pointer,
like we already do in multi_tcp_process_io().

This change will allow us later to pass an event_arg
object as event handler argument instead of a simple
integer value.
