drm/amdgpu: Fix error handling in slot reset

Browse source

[ Upstream commit b57c4ec98c ]

If the device has not recovered after slot reset is called, it goes to
out label for error handling. There it could make decision based on
uninitialized hive pointer and could result in accessing an uninitialized
list.

Initialize the list and hive properly so that it handles the error
situation and also releases the reset domain lock which is acquired
during error_detected callback.
