CVE-2024-42078: nfsd: initialise nfsd_info.mutex early.
requested to merge redhat/red-hat-ci-tools/kernel/bot-branches/centos-stream-9:backport-RHEL-51547-centos-stream-9-main into main
JIRA: https://issues.redhat.com/browse/RHEL-51547
CVE: CVE-2024-42078
nfsd: initialise nfsd_info.mutex early.
nfsd_info.mutex can be dereferenced by svc_pool_stats_start()
immediately after the new netns is created. Currently this can
trigger an oops.
Move the initialisation earlier before it can possibly be dereferenced.
Fixes: 7b207ccd9833 ("svc: don't hold reference for poolstats, only mutex.")
