Brian Behlendorf e8fd45a0f9 Add ddt_object_count() error handling ... The interface for the ddt_zap_count() function assumes it can never fail. However, internally ddt_zap_count() is implemented with zap_count() which can potentially fail. Now because there was no way to return the error to the caller a VERIFY was used to ensure this case never happens. Unfortunately, it has been observed that pools can be damaged in such a way that zap_count() fails. The result is that the pool can not be imported without hitting the VERIFY and crashing the system. This patch reworks ddt_object_count() so the error can be safely caught and returned to the caller. This allows a pool which has be damaged in this way to be safely rewound for import.
