small patch to avoid warning in gcc 6

[Reinoud Koornstra]

Hello Everybody,

A small patch that doesn't really do anything other than getting rid
of a warning in gcc 6.1.0.

drivers/gpu/drm/i915/i915_debugfs.c: In function ‘i915_dump_lrc’:
drivers/gpu/drm/i915/i915_debugfs.c:2060:6: warning: suggest explicit
braces to avoid ambiguous ‘else’ [-Wparentheses]
   if (ctx != dev_priv->kernel_context)
      ^

Thanks,

Reinoud.
