[PATCH 1/3] NFSD: Add toctree entry for NFSD IO modes docs

[Bagas Sanjaya]

Commit fa8d4e6784d1b6 ("NFSD: add
Documentation/filesystems/nfs/nfsd-io-modes.rst") adds documentation for
NFSD I/O modes, but it forgets to add toctree entry for it. Hence,
Sphinx reports:

Documentation/filesystems/nfs/nfsd-io-modes.rst: WARNING: document isn't included in any toctree [toc.not_included]

Add the entry.

Fixes: fa8d4e6784d1b6 ("NFSD: add Documentation/filesystems/nfs/nfsd-io-modes.rst")
