Add the missing unlock before return from function i915_gem_init_hw() in the error handling case.

Applied, thanks for the patch. Two minor comments: - Please mention the commit that introduced the issue next time around. I've added that while applying.
- The usual patter is
if (ret) goto out;
/* more code */
out: mutex_unlock(); return ret;
This would work really well in i915_gem_init_hw and besides the code-cleanup also prevents such a fumble in the future. If you feel like please submit that patch to convert init_hw to this shared unlock code pattern, too.
Thanks, Daniel
