ring-buffer: prevent adding write in discarded area
The ring buffer may now add discarded events when a write passes
the end of a buffer page. Before, a discarded event was only added
when the tracer deliberately created one. The ring buffer benchmark
test does not handle discarded events when it reads the buffer and
fails when it encounters one.
Also fix the increment for large data entries (luckily, the test did
not add any yet).
[ Impact: fix false failure of ring buffer self test ]
