[RFC 2/7] rt-tests: cyclictest: Simplify duplicate initialization of "stop"

[Punit Agrawal <punitagrawal@gmail.com>]

From: Punit Agrawal <punit1.agrawal@toshiba.co.jp>

The timespec structure "stop" is initialised whether it is used or not
as the compiler is not smart enough to figure out that it's use is
always guarded by the "duration" variable. As a result, "stop" needs
to be initialised whether it's used or not to avoid a compiler
warning.

Replace the duplicate memset statements by initializing "stop" using
structure initialiser.
