If the ZAP object containing a snapshot map is corrupted due to an unrecoverable checksum error or otherwise, dsl_dataset_name() will normally panic the system due to its VERIFY. This patch attempts to allow a recovery avenue from such situations by manufacturing a descriptive snapshot name and then ignoring the error. Scrubbing a pool with this type of corruption will then show the affected object in the error list rather than panicking. The recovery code is only enabled when the zfs_recover module parameter is set. Signed-off-by: Tim Chase <tim@chase2k.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #3705
