As explained by the comment of the fixed code, we need to find the next
bridge that hasn't set the "pre_enable_prev_first" flag to true. The code,
on the contrary, was doing the opposite.
So, the order of disabling the bridges couldn't be altered as required
by setting the "pre_enable_prev_first" flag to true.

Fixes: 4fb912e5e190 ("drm/bridge: Introduce pre_enable_prev_first to alter bridge init order")
