7147 ztest: ztest_ddt_repair fails with ztest_pattern_match assertion

Here's the dbuf we're currently reading:
966f200::dbuf
addr object lvl blkid holds os
966f200 4 0 0 1 ztest/ds_3
966f200::print dmu_buf_t db_data
db_data = 0x9ae0400
0x9ae0400/10J
0x9ae0400: c1c7ced932020d c1c7ced932020d c1c7ced932020d c1c7ced932020d
c1c7ced932020d c1c7ced932020d c1c7ced932020d c1c7ced932020d
c1c7ced932020d c1c7ced932020d
The pattern we're expecting is actually this: a34ae10b5f2db2. If we attempt to
read the block on disk we find that it has matches what ztest_ddt_repair()
would have written:
~c1c7ced932020d=J
