platform/x86: samsung-galaxybook: Fix block_recording not supported logic

Fixes logic error when block_recording is not supported but the fw attr was
being added anyway (reported by GitHub user bbregeault).

Tested myself on a Samsung Galaxy Book2 Pro (has block_recording) and by
bbregeault on a Galaxy Book2 Business (does not have block_recording).

Fixes: 56f529c ("platform/x86: samsung-galaxybook: Add samsung-galaxybook driver")
