Subject: [PATCH] ring-buffer: change WARN_ON from checking preempt_count to
 preemptible

There's a WARN_ON in the ring buffer code that makes sure preemption
is disabled. It checks "!preempt_count()". But when CONFIG_PREEMPT is not
enabled, preempt_count() is always zero, and this will trigger the warning.

[ Impact: prevent false warning on non preemptible kernels ]
