vfio: Fix broken EEH 



vfio_eeh_container_op() is the backend that communicates with
host kernel to support EEH functionality in QEMU. However, the
functon should return the value from host kernel instead of 0
unconditionally.

dwg: Specifically the problem occurs for the handful of EEH
sub-operations which can return a non-zero, non-error result.
