This partially reverts commit that made hfi_session_destroy()
the first step of vdec/venc close(). The reason being is a
regression report when, supposedly, encode/decoder is closed
with still active streaming (no ->stop_streaming() call before
close()) and pending pkts, so isr_thread cannot find instance
and fails to process those pending pkts. This was the idea
behind the original patch - make it impossible to use instance
under destruction, because this is racy, but apparently there
are uses cases that depend on that unsafe pattern. Return to
the old (unsafe) behaviour for the time being (until a better
fix is found).

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.
