Matthew Ahrens 2ade4a99f0 OpenZFS 8126 - ztest assertion failed in dbuf_dirty due to dn_nlevels changing 
The sync thread is concurrently modifying dn_phys->dn_nlevels
while dbuf_dirty() is trying to assert something about it, without
holding the necessary lock. We need to move this assertion further down
in the function, after we have acquired the dn_struct_rwlock.
