Subject: [PATCH][next][V3] rv: Fix addition on an uninitialized variable 'run'

The variable run is not initialized however it is being accumulated
by the return value from the call to ikm_run_monitor.  Fix this by
initializing run to zero at the start of the function.

Fixes: 4bc4b131d44c ("rv: Add rv tool")

Signed-off-by: Colin Ian King <colin.i.king@...il.com>

V2: Initialize run rather than assign it from return from ikm_run_monitor
V3: Add missing V3 and next in patch subject
