93f7636268 gpu: nvgpu: unit test mapping cache maint errors 
Target the recently extended error handling paths in gmmu mapping paths
in both passing and failing PTE entry update conditions. Verify the
number of calls to cache ops and that failed mappings leave the PTEs
cleared.

32a148867f gpu: nvgpu: unit test leaky failed mappings 
Ensure that when a mapping attempt fails in the middle of updating GMMU
PTEs, the PTEs are left unmapped. Add test_map_buffer_security() to the
VM tests to trigger a PD allocation failure and verify the first PTE.
