[libvirt] [PATCH] Add function that raises error if domain is not active

Add a function named virDomainObjCheckIsActive in src/conf/domain_conf.c.
It calls virDomainObjIsActive, raises error and returns.
There is a lot of occurence of this pattern and it will save 3 lines on
each call. Knowing that there is over 100 occurences, it will remove 300
lines from the code base.
