kernel: nfsd: initialise nfsd_info.mutex early.

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialise nfsdinfo.mutex early. nfsdinfo.mutex can be dereferenced by svcpoolstatsstart immediately after the new netns is created. Currently this can trigger an oops. Move the initialisation earlier before it can possibly...
