[PATCH 6.13 04/23] nfsd: fix legacy client tracking initialization

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Scott Mayhew <smayhew@redhat.com>

commit de71d4e211eddb670b285a0ea477a299601ce1ca upstream.

Get rid of the nfsd4_legacy_tracking_ops->init() call in
check_for_legacy_methods().  That will be handled in the caller
(nfsd4_client_tracking_init()).  Otherwise, we'll wind up calling
nfsd4_legacy_tracking_ops->init() twice, and the second time we'll
trigger the BUG_ON() in nfsd4_init_recdir().

Fixes: 74fd48739d04 ("nfsd: new Kconfig option for legacy client tracking")
