[libvirt] [PATCH 2/3] storage: driver: Split out code fixing pool state after deactivation

[Peter Krempa]

After a pool is made inactive the definition objects need to be updated
(if a new definition is prepared) and transient pools need to be
completely removed. Split out the code doing these steps into a separate
function for later reuse.
