Daniel T. Lee 2bf8c7e735 samples: bpf: Fix broken bpf programs due to removed symbol ...

>From commit f1394b7988 ("block: mark blk_account_io_completion
static") symbol blk_account_io_completion() has been marked as static,
which makes it no longer possible to attach kprobe to this event.
Currently, there are broken samples due to this reason.

As a solution to this, attach kprobe events to blk_account_io_done()
to modify them to perform the same behavior as before.
