NFS: switch back to using kill_anon_super

NFS switch to open coding kill_anon_super in 7b14a213890a
("nfs: don't call bdi_unregister") to avoid the extra bdi_unregister
call.  At that point bdi_destroy was called in nfs_free_server and
thus it required a later freeing of the anon dev_t.  But since
0db10944a76b ("nfs: Convert to separately allocated bdi") the bdi has
been free implicitly by the sb destruction, so this isn't needed
anymore.

By not open coding kill_anon_super, nfs now inherits the fix in
dc3216b14160 ("super: ensure valid info"), and we remove the only
open coded version of kill_anon_super.
