Description:
Node group can be configured by Nodegroup=number
However in some parts of the code one assumes that the
max node group number is equal to the number of node groups minus
one.

These checks should instead be checking that the node isn't ZNIL.

How to repeat:
Run Autotest daily-basic--01 with a configuration that sets a node group
id at least as big as the number of node groups.

Suggested fix:
Change checks of incorrect node group setting.
