Avoid crashing on multiple -incoming

Browse Source 
Passing multiple -incoming options used to crash qemu (due to
an invalid state transition incoming->incoming).  Instead we now
take the last -incoming option, e.g.:

qemu-system-x86_64 -nographic -incoming tcp::4444 -incoming defer

ends up doing the defer.
