gru: check context state on reload
Check whether the gru state being loaded into a gru is from a new context
or a previously unloaded context. If new, simply zero out the hardware
context; if unloaded and valid, reload the old state.
This change is primarily for reloading kernel contexts where the previous
is not required to be saved.
