[PATCH] arm64: cacheinfo: Simplify init_cache_level()

[Thorsten Blum <blum@kernel.org>]

acpi_get_cache_info() already sets fw_level to 0 on failure, so drop the
redundant check and the manual assignment.

Use unsigned int for fw_level to match the expected type, and remove the
now-unused local ret variable.
