Alberto Garcia 0c2ada8136 qcow2: Make qemu-img check detect corrupted L1 tables in snapshots 
'qemu-img check' cannot detect if a snapshot's L1 table is corrupted.
This patch checks the table's offset and size and reports corruption
if the values are not valid.

This patch doesn't add code to fix that corruption yet, only to detect
and report it.
