[PATCH 2/4] gnttab: Fix memory leak in failure path

[Owen Smith <owen.smith@xxxxxxxxx>]

From: david ambu <david.preetham@xxxxxxxxx>

In certain error paths, the context memory was not being released,
causing a potential memory leak. Ensure that __GnttabFree() is called
on failure to properly release resources and reset the context.
Free Context during failure paths
Allocated memory is freed during failure case.
