Beside umc, others' UE interrupt callback could enter into amdgpu_ras_reset_gpu,
so the first patch change to save bad pages in UMC error interrupt callback.

When bad page error happens, the bad page mostly still be hold by some
process, therefore driver will fail to reserve the bad page. The third
patch will reserve the bad page when freeing it, make system has no
chance to allocate it to other proccess.

  drm/amdgpu: change to save bad pages in UMC error interrupt callback
  drm/amdgpu: remove redundant GPU reset
  drm/amdgpu: fix the issue of reserving bad pages failed
