The error handling for virtual functions assumed a single
vf per VM and didn't properly account for bare metal. Make
the error arrays per device and add locking.

drm/amdgpu: Support passing amdgpu critical error to host via GPU Mailbox.2017-07-14T15:05:52+00:00Gavin WanGavin.Wan@amd.com2017-06-23T17:55:15+00:00urn:sha1:890419409a3aba2ca7185a824e47d8ded8df11a2
This feature works for SRIOV enviroment. For non-SRIOV enviroment, the
trans_error function does nothing.
The error information includes error_code (16bit), error_flags(16bit)
and error_data(64bit). Since there are not many errors, we keep the
errors in an array and transfer all errors to Host before amdgpu
initialization function (amdgpu_device_init) exit.
