Fix auditing of disk hotunplug operations
Fix auditing of disk hotunplug operations

The qemuAuditDisk calls in disk hotunplug operations were being
passed 'ret >= 0', but the code which sets ret to 0 was not yet
executed, and the error path had already jumped to the 'cleanup'
label. This meant hotunplug failures were never audited, and
hotunplug success was audited as a failure
