Fix DRBD version check for non VM capable nodes

Commit 742dc8de revealed a bug concerning DRBD version check during
cluster verify: In case non VM cabables nodes have DRBD not
installed, we get a version mismatch warning.

VerifyNode() updates the NV_DRBDVERSION key in the response message
only if a node is VM capable. Even if noded fails to retrieve the
DRBD version, the error string is returned.

Thus we must first check in _VerifyGroupDRBDVersion() if the
NV_DRBDVERSION key of the response message is updated and
then verify if we have different versions across nodes.
