[igt-dev] [PATCH i-g-t 1/4] tools/intel_gpu_top: Fix clients header width when no clients

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Recent refactoring broke the clients header in cases when there are no
clients displayed. To fix it we need to account the width of the "NAME"
label.
