napi_disable uses an msleep() call to wait for outstanding napi work to be finished after setting the disable bit. It does not always sleep incase there was no outstanding work. This resulted in a rare bug in ixgbe_down operation where a napi_disable call took place inside of a local_bh_disable()d context. In order to enable easier detection of future sleep while atomic BUGs, this patch adds a might_sleep() call, so that every use of napi_disable during atomic context will be visible.
