Tim Chase d439f63ff5 Allow recovery from corrupted snapshot maps ...

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.
