[PATCH 5.10 8/8] perf intel-pt: Fix error timestamp setting on the decoder error path

[Adrian Hunter <adrian.hunter@intel.com>]

commit 6665b8e4836caa8023cbc7e53733acd234969c8c upstream.

An error timestamp shows the last known timestamp for the queue, but this
is not updated on the error path. Fix by setting it.
