Matthew Ahrens 3c2a42fd25 dedup=verify doesn't clear the blkptr's dedup flag
The logic to handle strong checksum collisions where the data doesn't
match is incorrect. It is not clearing the dedup bit of the blkptr,
which can cause a panic later in zio_ddt_free() due to the dedup table
not matching what is in the blkptr.
