... unless you first unload the current DRBD module as well,
or use rpm -e --noscript.

Which in fact is intentional, to prevent people from "accidentally"
uninstall a module package while the provided module is still in use
(it may have been symlinked in place into some other kernel version
 by some weak-module magic, or explicitly).

But yes, it may be annoying at times.

So maybe
filename=$(modinfo -F filename drbd)
filename=$(readlink "$filename")
rpm -qf $filename
and check if that is in fact the current package?
