Fix a bug where we used to not initialize the cached fid structure at all in open_shroot() if the open was successful but we did not get a lease. This would leave the structure uninitialized and later when we close the handle we would in close_shroot() try to kref_put() an uninitialized refcount. Fix this by always initializing this structure if the open was successful but only do the extra get() if we got a lease. This extra get() is only used to hold the structure until we get a lease break from the server at which point we will kref_put() it during lease processing.

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 Restructured Text 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.
