[libvirt] [PATCH 09/26] virsh: Resolve Coverity DEADCODE
Coverity points out that by using EMPTYSTR(type) we are guarding against
the possibility that it could be NULL; however, based on how 'type' was
initialized to NULL, then either "ipv4", "ipv6", or "" -
there is no way
it could be NULL. Since "-" is supposed to mean something empty in a
field - remove the initialization to NULL and use it as the ending else
rather than using "".
Also changed the name from 'type' to 'typestr'.
