This patch updates the fbcon_skip_panic() function to use the
panic_in_progress() helper.

The previous direct access to panic_cpu is less readable and is being
replaced by a dedicated function that more clearly expresses the intent.

This change is part of a series to refactor the kernel's panic handling
logic for better clarity and robustness.
