Currently, raw zfs sends transfer the encrypted master keys and objset_phys_t encryption parameters in the DRR_BEGIN payload of each send file. Both of these are processed as soon as they are read in dmu_recv_stream(), meaning that the new keys are set before the new snapshot is received. In addition to the fact that this changes the user's keys for the dataset earlier than they might expect, the keys were never reset to what they originally were in the event that the receive failed. This patch splits the processing into objset handling and key handling, the later of which is moved to dmu_recv_end() so that they key change can be done atomically.
