The zio returned from arc_write() in dmu_objset_sync() uses zio_nowait(). However we may reach the end of dsl_dataset_sync() which checks if we need to activate features in the filesystem without knowing if that zio has even run through the ZIO pipeline yet. In that case we will flag features to be activated in dsl_dataset_block_born() but dsl_dataset_sync() has already completed its run and those features will not actually be activated. Mitigate this by moving the feature activation code in dsl_dataset_sync_done(). Also add new ASSERTs in dsl_scan_visitbp() checking if a block contradicts any filesystem flags.

With commit 34ce4c4 applied, there is no need for eee9362. Revert that aside from the test. All tests introduced in those commits pass.

Otherwise the dataset may be freed after the last dmu_buf_rele() leading to a panic. Reviewed-by: Mark Maybee <mark.maybee@delphix.com> Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Signed-off-by: George Amanakis <gamanakis@gmail.com> Closes openzfs#14522 Closes openzfs#14523
