Alexander Motin 85ce6b8ab2 Polish db_rwlock scope
dbuf_verify(): Don't need the lock, since we only compare pointers.

dbuf_findbp(): Don't need the lock, since aside of unneeded assert
we only produce the pointer, but don't de-reference it.

dnode_next_offset_level(): When working on top level indirection
should lock dnode buffer's db_rwlock, since it is our parent.  If
dnode has no buffer, then it is meta-dnode or one of quotas and we
should lock the dataset's ds_bp_rwlock instead.
