Call compute manager methods with instance as keyword argument
Call compute manager methods with instance as keyword argument

reverts_task_state and wrap_instance_fault both expect to be able to
find an instance keyword argument if an exception is raised while
executing the wrapped function.

Fix stop_instance and start_instance to call other compute manager
methods with instance as a keyword argument to ensure the decorators
correctly function.

Only the nested call to the decorated function didn't have the instance
keyword argument. As a result, the initial call would correctly
perform the decorated functions. This fix will ensure that spurious
and confusing log messages don't get generated.
