[PATCH 6.1 1/6] Revert "NFS: More fixes for nfs_direct_write_reschedule_io()"

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This reverts commit edd1f06145101dab83497806bb6162641255ef50 which is
commit b11243f720ee5f9376861099019c8542969b6318 upstream.

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