Cleanups in sunrpc code from NIIBE Yutaka <gniibe@mri.co.jp>.

	* sunrpc/clnt_tcp.c (clnttcp_create): Don't close *SOCKP if it's -1.
	* sunrpc/clnt_simp.c (callrpc): Don't close CRP->socket if it's
	RPC_ANYSOCK.
	* sunrpc/pmap_clnt.c (pmap_set): Don't close SOCKET, since
	CLNT_DESTROY already has.
	(pmap_unset): Likewise.
	* sunrpc/pm_getmaps.c (pmap_getmaps): Likewise.
	* sunrpc/pm_getport.c (pmap_getport): Likewise.
	* sunrpc/pmap_rmt.c (pmap_rmtcall): Likewise.
	* sunrpc/portmap.c (callit): Likewise.
