virFileOperation previously returned 0 on success, or the value of
errno on failure. Although there are other functions in libvirt that
use this convention, the preferred (and more common) convention is to
return 0 on success and -errno (or simply -1 in some cases) on
failure. This way the check for failure is always (ret<  0).

* src/util/util.c - change virFileOperation and virFileOperationNoFork to
                     return -errno on failure.

* src/storage/storage_backend.c, src/qemu/qemu_driver.c
   - change the hook functions passed to virFileOperation to return
     -errno on failure.
   ACK,

Pushed. Thanks!
