svcrpc: never clear XPT_BUSY on dead xprt 

Once an xprt has been deleted, there's no reason to allow it to be
enqueued--at worst, that might cause the xprt to be re-added to some
global list, resulting in later corruption.

Also, note this leaves us with no need for the reference-count
manipulation here.
