[Intel-gfx] [PATCH] drm/i915: remove duplicated memsets in skl_allocate_pipe_ddb()

[Paulo Zanoni]

One of the memsets was added by 5a920b85f2c6 ("drm/i915/gen9: fix DDB
partitioning for multi-screen cases"), and the other was added by
01c72d6c17 ("drm/i915/gen9: fix DDB partitioning for multi-screen
cases"). I'm confused and I'll let the maintainers find out what went
wrong here.
