Fix raw sends on encrypted datasets when copying back snapshots
When sending raw encrypted datasets the user space accounting is present when it's not expected to be. This leads to the subsequent mount failure due a checksum error when verifying the local mac. Fix this by clearing the OBJSET_FLAG_USERACCOUNTING_COMPLETE and reset the local mac. This allows the user accounting to be correctly updated on first mount using the normal upgrade process.

| # DESCRIPTION: | ||
| # Sending raw encrypted datasets back to the source dataset succeeds. | ||
| # | ||
| # | ||
| # STRATEGY: | ||
| # 1. Create encrypted source dataset, set userquota and write a file | ||
| # 2. Create base and an additional snapshot (s1) | ||
| # 3. Unmount the source dataset | ||
| # 4. Raw send the base snapshot to a new target dataset | ||
| # 5. Raw send incrementally the s1 snapshot to the new target dataset | ||
| # 6. Mount both source and target datasets | ||
| # 7. Verify encrypted datasets support 'zfs userspace' and 'zfs groupspace' | ||
| # and the accounting is done correctly | ||
