This patch fixes 2 issues with raw, deduplicated send streams. The first is that datasets who had been completely received earlier in the stream were not still marked as raw receives. This caused problems when newly received datasets attempted to fetch raw data from these datasets without this flag set. The second problem was that the arc freeze checksum code was not consistent about which locks needed to be held while performing its asserts. The proper locking needed to run these asserts is actually fairly nuanced, since the asserts touch the linked list of buffers (requiring the header lock), the arc_state (requiring the b_evict_lock), and the b_freeze_cksum (requiring the b_freeze_lock). This seems like a large performance sacrifice and a lot of unneeded complexity to verify that this relatively small debug feature is working as intended, so this patch simply removes these asserts instead.
