[PATCH v8 03/43] drm: fix config dependent unused variable warning.

From: Jim Cromie <jim.cromie@gmail.com>

__drm_printfn_dbg() does
  int category = p->category;
then does:
  if (drm_debug_enabled(category))

When CONFIG_DRM_USE_DYNAMIC_DEBUG=y, that macro doesn't reference the
category arg, because its optimized away, as not needed when dyndbg's
static-key is under the callsite.  Silence the warning by passing
p->category directly.
