[PATCH 4/6] Fix possible memory leak in virsh-domain-monitor.c

[Pavel Hrdina <phrdina@xxxxxxxxxx>]

In a "for" loop there are created two new strings and they may not
be freed if a "target" string cannot be obtained. We have to free
the two created strings to prevent the memory leak.

This has been found by coverity.
