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

[Why]
Opening the CRC data file during active rendering can fail with -EINVAL.

Closing the CRC data file with ctrl+C (which will send SIGINT to the kernel
and if the wait thread in sleep, kernel will send the -ERESTARTSYS to the
wait_for_completion_interruptible_timeout)
resulting in intermittently getting -ERESTARTSYS. which will just do the
clean up without releasing the vblank reference causing -EINVAL while opening
the crc data file in the next iteration

[How]
Ignoring the ERESTARTSYS as this is a return value for the
wait_for_completion_interruptible_timeout()
