xend: canonicalise symlinks found in /dev for vbds (helps vscsi)
By default, vscsi expects to be passed the final device name (eg
/dev/st3) instead of one of the various udev symlinks (eg
/dev/tape/by-path/pci-0000:01:08.0-scsi-0:0:2:0-st). The following patch
resolves the path to the real path if the name starts with /dev/
