[libvirt] [PATCHv2 04/13] Consistently return 0 on success, -1 on failure in bridge_driver.c
Some functions in this file were returning 1 on success and 0 on
failure, and others were returning 0 on success and -1 on
failure. Switch them all to return the libvirt-preferred 0/-1.

No changes from V1.
