[Intel-gfx] [PATCH v3 2/2] drm/i915/skl+: Update result lines in correspondence with result blocks

[Karthik B S]

As the result blocks for WM1-WM7 are always kept higher than the
level below the present level, make sure result lines are also higher
than the level below for WM1-WM7.

V3: Updated the commit message.
