commit e75d18cecbb3 ("arm64: cacheinfo: Fix incorrect assignment of signed error value to unsigned fw_level") checks the fw_level value in init_cache_level() in case the value is negative. Remove this check as the error code is not returned through fw_level anymore, and reset fw_level if acpi_get_cache_info() failed. This allows to try fetching the cache information from clidr_el1.
