Subject: [PATCH] Stop n-cpu by correct process name /w fake

When VIRT_DRIVER=fake, n-cpu processes are numbered (ie, n-cpu-1) in
start_nova. However, this scheme is not taken into account when
stopping nova, resulting in leftover n-cpu processes that fail
grenade's stop-base if USE_SCREEN=False. This special cases for the
fake driver in stop_nova_compute and ensures n-cpu(s) is shutdown
correctly.
