Revert "NFS: Use the correct commit info in nfs_join_page_group()"

This reverts commit d4729af1c73cfacb64facda3d196e25940f0e7a5 which is
commit b193a78ddb5ee7dba074d3f28dc050069ba083c0 upstream.

There are reported NFS problems in the 6.1.56 release, so revert a set
of NFS patches to hopefully resolve the issue.
