Kill off the hack that parses info_str for the tap interface
name to pass as the argument to the downscript and, instead,
just explicitly keep a copy of the string for later.
As reported by John Wong, this commit:
Add qemu_format_nic_info_str()
changed the invocation of downscript from e.g.
/path/kvm-ifdown "tap0"
to:
/path/kvm-ifdown "tap0,script=/path/kvm-ifup,downscript=/path/kvm-ifdown"
This fix restores the original behavior.
