Subject: [PATCH v3 1/7] media: ipu-bridge: Fix warning when !ACPI

One of the quirks that we introduced to build with !ACPI && COMPILE_TEST
throws the following smatch warning:
drivers/media/pci/intel/ipu-bridge.c:752 ipu_bridge_ivsc_is_ready() warn: iterator 'i' not incremented

Fix it by replacing the condition.
