John Harrison 960f20d858 drm/i915/guc: Fix locking when searching for a hung request 
[ Upstream commit 87b04e53daf806945c415e94de9f90943d434aed ]

intel_guc_find_hung_context() was not acquiring the correct spinlock
before searching the request list. So fix that up. While at it, add
some extra whitespace padding for readability.

Fixes: dc0dad365c ("drm/i915/guc: Fix for error capture after full GPU reset with GuC")
