tsan: test: Initialize all fields of Params struct

[melver]

Summary

Some compilers started complaining about the test:

tsan_trace_test.cpp:128:21: error: missing field 'type' initializer

Fix it by initializing all 5 fields, even though the type field will be
reset in the for loop.

Awesome! Thanks!
