[PATCH] SUNRPC: Make sure authorize svc when meeting SVC_CLOSE

[Kinglong Mee <kinglongmee@gmail.com>]

Commit 4d712ef1db05 "svcauth_gss: Close connection when
 dropping an incoming message" will close connection,
but forget authorizing the svc when meeting SVC_CLOSE.

That, there will be an module reference to sunrpc,
and some memory leak.

When mounting an nfs filesystem, the reference leak increase one.
