nfsd: initialise nfsd_info.mutex early.

Browse source

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: 7b207ccd98 ("svc: don't hold reference for poolstats, only mutex.")
