tracing/probes: Fix probe event argument parser

These fix two bugs in the trace probe event argument parser, which I found while I'm cleaning up the code.

One is just adding an error message to message log buffer (but it is important to check the reason). Another is setting the size of argument entry correctly with argument data updated by BTF.

Thank you,
