During a GPU reset, a normal memory reclaim could block to reclaim
memory. Giving that coredump is a best effort mechanism, it shouldn't
disturb the reset path. Change its memory allocation flag to a
nonblocking one.

Since it is a bug fix I've already pushed this one into our internal branch quite a while ago.

Shashank can you take care of picking up the remaining patches and pushing them to amd-staging-drm-next?

Thanks,
Christian.
