refscale: Warn on individual ref_scale_init() error conditions
When running refscale as a module, any ref_scale_init() issues will be
reflected in the error code from modprobe or insmod, as the case may be.
However, these error codes are not available when running refscale
built-in, for example, when using the kvm.sh script. This commit
therefore adds WARN_ON_ONCE() to allow distinguishing ref_scale_init()
errors when running refscale built-in.
