backlight: mp3309c: Fix signedness bug in mp3309c_parse_fwnode()

The "num_levels" variable is used to store error codes from
device_property_count_u32() so it needs to be signed.  This doesn't
cause an issue at runtime because devm_kcalloc() won't allocate negative
sizes.  However, it's still worth fixing.
