In the existing code, when doing a raw (encrypted) zfs receive, we call arc_convert_to_raw() from open context. This creates a race condition between arc_release()/arc_change_state() and writing out the block from syncing context (arc_write_ready/done()). This change makes it so that when we are doing a raw (encrypted) zfs receive, we save the crypt parameters (salt, iv, mac) of dnode blocks in the dbuf_dirty_record_t, and call arc_convert_to_raw() from syncing context when writing out the block of dnodes. Additionally, we can eliminate dr_raw and associated setters, and instead know that dnode blocks are always raw when doing a zfs receive (see the new field os_raw_receive).
