[RFC PATCH -next 14/16] mm/damon/core: convert sz to byte units when updating state

[Quanmin Yan]

After introducing ctx->addr_unit, the unit of sz might not
be in bytes. However, sz_applied is returned in bytes after
processing by paddr. To maintain external consistency, sz
is converted to byte units when updating the state.
