[PATCH 3/3] crypto: tcrypt - yield at end of test

[Robert Elliott]

Call cond_resched() to let the scheduler reschedule the
CPU at the end of each test pass.

If the kernel is configured with CONFIG_PREEMPT_NONE=y (or
preempt=none is used on the kernel command line), the only
time the scheduler will intervene is when cond_resched()
is called. So, repeated calls to
	modprobe tcrypt mode=<something>

hold the CPU for a long time.
