Nirmoy Das 476b3f03dc drm/i915/active: Fix missing debug object activation 
commit e92eb246fe upstream.

debug_active_activate() expected ref->count to be zero
which is not true anymore as __i915_active_activate() calls
debug_active_activate() after incrementing the count.

v2: No need to check for "ref->count == 1" as __i915_active_activate()
already make sure of that(Janusz).

README 

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.
