Previously KUnit assumed that printk would always be present, which is not a valid assumption to make. Fix that by removing call to vprintk_emit, and calling printk directly. This fixes a build error[1] reported by Randy. For context this change comes after much discussion. My first stab[2] at this was just to make the KUnit logging code compile out; however, it was agreed that if we were going to use vprintk_emit, then vprintk_emit should provide a no-op stub, which lead to my second attempt[3]. In response to me trying to stub out vprintk_emit, Sergey Senozhatsky suggested a way for me to remove our usage of vprintk_emit, which led to my third attempt at solving this[4]. In my third version of this patch[4], I completely removed vprintk_emit, as suggested by Sergey; however, there was a bit of debate over whether Sergey's solution was the best. The debate arose due to Sergey's version resulting in a checkpatch warning, which resulted in a debate over correct printk usage. Joe Perches offered an alternative fix which was somewhat less far reaching than what Sergey had suggested and importantly relied on continuing to use %pV. Much of the debated centered around whether %pV should be widely used, and whether Sergey's version would result in object size bloat. Ultimately, we decided to go with Sergey's version.
