nfsd: unregister with rpcbind when deleting a transport
[ Upstream commit 898374fdd7f06fa4c4a66e8be3135efeae6128d5 ]
When a listener is added, a part of creation of transport also registers
program/port with rpcbind. However, when the listener is removed,
while transport goes away, rpcbind still has the entry for that
port/type.
When deleting the transport, unregister with rpcbind when appropriate.
---v2 created a new xpt_flag XPT_RPCB_UNREG to mark TCP and UDP
transport and at xprt destroy send rpcbind unregister if flag set.
