[libvirt] [PATCH 6/6] EAFP: Coverity cleanup

A new version of Coverity found:

get_dev_from_pool(): RESOURCE_LEAK
  - Because the code is run within a for() loop Coverity complains
    that the returned 'poolid' is not free'd during each pass through
    the loop.  So even though it may not be fetched again, just free()
    and reinitialize 'poolid' after usage
