sunrpc: pass in the sv_stats struct through svc_create_pooled

Browse Source 
[ Upstream commit f094323867 ]

Since only one service actually reports the rpc stats there's not much
of a reason to have a pointer to it in the svc_program struct.  Adjust
the svc_create_pooled function to take the sv_stats as an argument and
pass the struct through there as desired instead of getting it from the
svc_program->pg_stats.
