[PATCH i-g-t] tests/xe_eudebug_online: Ignore stale attention events during single-step

[Dominik Grzegorzek]

Signle step testcases are not filtering stale attention events in
resume trigger, as a result those expect fixed number of attention
events to come. If for some reason attention wasn't handeled before the
next one came test would fail. Filter out all atentions with seqno
lower than last eu control call.
