drm/amd/display: Fix CRC open failure during active rendering

Browse source

[Why]
Opening the CRC data file during active rendering can fail with -EINVAL.
The wait for commit->hw_done returns remaining jiffies on success, but
the CRC path was treating that as an error.

[How]
Handle wait_for_completion_interruptible_timeout() correctly:
positive return as success, 0 as timeout, and negative as error.
