tracing: Fix minor typos in samples header

Following minor corrections in the comments section of the trace events sample header file.

- There are 6 parts of the TRACE_EVENT macro instead of 5 (name, TP_PROTO, TP_ARGS, TP_STRUCT, TP_fast_assign, TP_printk).

- The example variable for __field_struct type should be the variable name instead of the variable.

- Improve closing brace alignment to improve readability.
