Removed superfluous dcheck.

Removed superfluous dcheck.

Removed dcheck from HandleShowSyncSetup() because the promo page likes to call this routine when it's loaded/reloaded. There's no harm in calling this twice since OpenSyncSetup() handles the case when the overlay is already visible.

The other half of this bug is r125797 - if we reload the page, then before the page is reloaded the original SyncSetupHandler should get some kind of a notification so it can unregister itself from LoginUIService.

BUG=129490
TEST=Signin to acct with custom passphrase via promo, when prompted for passphrase hit reload, should not get a crash.

Just a quick one-line fix (deleted dcheck).
