drm/i915/guc: Fix release build bug in 'remove log size module parameters'

A patch was merged to remove the GuC log size override module
parameters. That patch was broken and caused kernel error messages on
boot in non CONFIG_DEBUG_GUC|GEM builds:
[   12.085121] i915 0000:00:02.0: [drm] *ERROR* Zero GuC log crash dump size!
[   12.092035] i915 0000:00:02.0: [drm] *ERROR* Zero GuC log debug size!

So fit it.
