drm/amdgpu: Reset error code for 'no handler' case
If reset handler is not implemented, reset error before proceeding.
Fixes issue with the following trace -
[ 106.508592] amdgpu 0000:b1:00.0: amdgpu: ASIC reset failed with error, -38 for drm dev, 0000:b1:00.0
[ 106.508972] amdgpu 0000:b1:00.0: amdgpu: GPU reset succeeded, trying to resume
[ 106.509116] [drm] PCIE GART of 512M enabled.
[ 106.509120] [drm] PTB located at 0x0000008000000000
[ 106.509136] [drm] VRAM is lost due to GPU reset!
[ 106.509332] [drm] PSP is resuming...
