[libvirt] [PATCH 1/2] util: Accept test data path for scsi device's sg_path

[Osier Yang]

Commit 10c9ceff6d intended to introduce new argument for the
testing purpose, but it missed the similar changing of the
device's sg_path. The problem was hidden since my laptop has
the /dev/sg0 and /dev/sg1.  A later patch will modify the tests
accordingly.
