[libvirt] [PATCH v2 4/7] virsh-interface: Resolve Coverity issues

Recent changes uncovered FORWARD_NULL and NEGATIVE_RETURNS problems with
the processing of the 'nActiveIfaces' and 'nInactiveIfaces' and their
associated allocated arrays in 'vshInterfaceListCollect' due to the
possibility of returning -1 in a call and using the return value as a
for loop index end condition.
