Tom Caputi 440a3eb939 Fixes for #6639 ... Several issues were uncovered by running stress tests with zfs encryption and raw sends in particular. The issues and their associated fixes are as follows: * arc_read_done() has the ability to chain several requests for the same block of data via the arc_callback_t struct. In these cases, the ARC would only use the first request's dsobj from the bookmark to decrypt the data. This is problematic because the first request might be a prefetch zio which is able to handle the key not being loaded, while the second might use a different key that it is sure will work. The fix here is to pass the dsobj with each individual arc_callback_t so that each request can attempt to decrypt the data separately. * DRR_FREE and DRR_FREEOBJECT records in a send file were not having their transactions properly tagged as raw during raw sends, which caused a panic when the dbuf code attempted to decrypt these blocks. * traverse_prefetch_metadata() did not properly set ZIO_FLAG_SPECULATIVE when issuing prefetch IOs. * Added a few asserts and code cleanups to ensure these issues are more detectable in the future.
