Stop waiting for the KIQ to return back when there is a reset pending.
It's quite likely that the KIQ will never response.

drm/amdgpu: fix locking scope when flushing tlb2024-06-14T20:15:59ZYunxiang LiYunxiang.Li@amd.com2024-05-23T11:48:19Zurn:sha1:9c33e5fd4fb63b793d9a92bf35d190630d9bada4
Which method is used to flush tlb does not depend on whether a reset is
in progress or not. We should skip flush altogether if the GPU will get
reset. So put both path under reset_domain read lock.

Here since we are in reset and takes the reset_domain write side lock
already. We can't use the flush tlb helper which tries to take the read
side.

drm/amdgpu: Remove GC HW IP 9.3.0 from noretry=12024-05-17T21:40:38ZTim Van Pattentimvp@google.com2024-05-16T17:57:25Zurn:sha1:1446226d32a45bb7c4f63195a59be8c08defe658
The following commit updated gmc->noretry from 0 to 1 for GC HW IP
9.3.0:
commit 5f3854f1f4e2 ("drm/amdgpu: add more cases to noretry=1")
This causes the device to hang when a page fault occurs, until the
device is rebooted. Instead, revert back to gmc->noretry=0 so the device
is still responsive.
