[Pkg-xen-devel] Bug#687319: #687319 also fixes local-SR mounting of ISOs, not just from NFS

[Per Andre Wilhelmsen]

Mounting ISOs now works as designed when using "local SR"-storage of ISO's 
too.
Example local SR created (from cli) :
   xe sr-create name-label=isostorage type=iso 
device-config:location=/home/isostorage device-config:legacy_mode=true 
content-type=iso shared=true
   xe sr-scan UUID=<UUID given from the above>

ISO-files are now available and listed properly in xencenter and from cli, 
and devices are handled appropriately in the VM as it should:

   lrwxrwxrwx 1 root root 4 Nov  7 23:39 /dev/cdrom -> xvdd
   brw-rw---- 1 root cdrom 202, 48 Nov  7 23:39 /dev/xvdd

Mounting local SR image shows that it is read correctly:

   mount: block device /dev/xvdd is write-protected, mounting read-only
   ISO 9660 Extensions: Microsoft Joliet Level 3
   ISO 9660 Extensions: RRIP_1991A

Unmounting unit also works as designed, with udev cleaning up /dev/cdrom and 
/dev/xvdd as it should.
