[PATCH] RPC: client-side transport switch cleanup
Clean-up: change some comments to reflect the realities of the new RPC
transport switch mechanism. Get rid of unused xprt_receive() prototype.
Also, organize function prototypes in xprt.h by usage and scope.
Test-plan:
Compile kernel with CONFIG_NFS enabled.
