drm/i915: Always recompute watermarks when distrust_bios_wm is set, v2.
On some systems there can be a race condition in which no crtc state is
added to the first atomic commit. This results in all crtc's having a
null DDB allocation, causing a FIFO underrun on any update until the
first modeset.
Changes since v1:
- Do not take the connection_mutex, this is already done below.
