[Intel-gfx] [PATCH v2 1/5] drm/i915/guc: Fix GuC relay log debugfs failing open

[Alan Previn]

When GuC-Error-Capture was introduced, we created
buf_in_use as a way to identify if relay logging
had started. It is meant to replace the previous
method where a mmap of the GuC log buffer was
the indicator but not since GuC Error Capture
shares that mapping throughout operation.

However, that method of checking was not updated
when the debugfs guc_log_relay_ctl_open was called.
Fix that check.
