[PATCH v7 04/20] tracing/remotes: Initialise pos in trace_start()

[Vincent Donnefort <vdonnefort@google.com>]

When *pos is 0, trace_start() passes a dummy local variable i to
trace_next() to fetch the first entry without modifying *pos. In that
branch, i was left uninitialized.

While i is discarded and causes no functional issues, initialise i and
keep static analysers happy.
