module: already_uses() - reduce pr_debug output volume
already_uses() is unnecessarily chatty.
`modprobe i915` yields 491 messages like:
[ 64.108744] i915 uses drm!
This is a normal situation, and isn't worth all the log entries.
NOTE: I've preserved the "does not use %s" messages, which happens
less often, but does happen. Its not clear to me what it tells a
reader, or what info might improve the pr_debug's utility.
