nfsd/sunrpc: add a new svc_serv_ops struct and move sv_shutdown into it

Browse Source 
In later patches we'll need to abstract out more operations on a
per-service level, besides sv_shutdown and sv_function.

Declare a new svc_serv_ops struct to hold these operations, and move
sv_shutdown into this struct.
