[Intel-gfx] [PATCH] drm/i915: intel_overlay_print_error_state() only needed for debugfs

[Tobias Doerffel]

The function intel_overlay_print_error_state() is called from within
i915_error_state() in i915_debufs.c which is only built if
CONFIG_DEBUG_FS is set. When building without this option, seq_printf()
is not declared in intel_overlay.c and the file fails to compile.
Furthermore the whole function is superfluous in this case. Therefore
only build it if CONFIG_DEBUG_FS is set.
