[PATCH 06/10] lib traceevent: Show contents (in hex) of data of unrecognized type records

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>

When a record has an unrecognized type, an error message is reported, but it
would also be helpful to see the contents of that record. At least show what
it is in hex, instead of just showing a blank line.
