drm/i915: Build request info on stack before printk
printk unhelpfully inserts a '\n' between consecutive calls, and since our drm_printf wrapper may be emitting info a seq_file instead, KERN_CONT is not an option. To work with any drm_printf destination, we need to build up the output into a temporary buf on the stack and then feed the complete line in a single call to printk.
