[PATCH v5 2/6] drm/i915/gen8: Re-order init pipe_control in lrc mode

[Arun Siluvery <arun.siluvery@linux.intel.com>]

Some of the WA applied using WA batch buffers perform writes to scratch page.
In the current flow WA are initialized before scratch obj is allocated.
This patch reorders intel_init_pipe_control() to have a valid scratch obj
before we initialize WA.
