BUG/MINOR: server: move the directive #endif to the end of file

If a source file includes proto/server.h twice or more, redefinition errors will
be triggered for such inline functions as server_throttle_rate(),
server_is_draining(), srv_adm_set_maint() and so on. Just move #endif directive
to the end of file to solve this issue.
