cacheinfo: Remove unused check in init_cache_level() 



commit e75d18ce ("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.
