netfs: Fix ref leak on inserted extra subreq in write retry
The write-retry algorithm will insert extra subrequests into the list if it
can't get sufficient capacity to split the range that needs to be retried
into the sequence of subrequests it currently has (for instance, if the
cifs credit pool has fewer credits available than it did when the range was
originally divided).

However, the allocator furnishes each new subreq with 2 refs and then
another is added for resubmission, causing one to be leaked.

Fix this by replacing the ref-getting line with a neutral trace line.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
