Revert "sunrpc: move the close processing after do recvfrom method"

Browse Source 
This reverts commit b0401d7253, which
moved svc_delete_xprt() outside of XPT_BUSY, and allowed it to be called
after svc_xpt_recived(), removing its last reference and destroying it
after it had already been queued for future processing.
