[PATCH 35/38] trace-cmd: move the initialization of found_pid at the beginning of stop_trace_connect()

In stop_trace_connect(), trace_fields.found_pid is used in the error
path before it has been initialized. Move the initialization at the
beginning of the function.

Fixes a UNINIT error (CWE-457)
