Send / Recv Fixes following b52563

Browse Source 
This patch fixes several issues discovered after
the encryption patch was merged:

* Fixed a bug where encrypted datasets could attempt
  to receive embedded data records.

* Fixed a bug where dirty records created by the recv
  code wasn't properly setting the dr_raw flag.

* Fixed a typo where a dmu_tx_commit() was changed to
  dmu_tx_abort()

* Fixed a few error handling bugs unrelated to the
  encryption patch in dmu_recv_stream()
