Fixes to known failures

[PaulAlbon]

Unit_hipGraphClone_Negative

• Issue: no handling of the nullptr cases

• Solution: Added nullptr check in CHIPBindings.cc, function hipGraphClone

Unit_HipDeviceGetCacheConfig_Negative_Parameters

• Issue: incorrect handling of nullptr case – it used NULLCHECK macro which returned “hipErrorInvalidHandle” instead of “hipErrorInvalidValue”

• Solution: Added manual nullptr check in CHIPBindings.cc, function hipDeviceGetCacheConfig

Unit_hipDeviceGetDefaultMemPool_Negative_Parameters

• Issue: function is not implemented (not handling nullptr and invalid device cases)

• Solution: implemented function hipDeviceGetDefaultMemPool to handle nullptr case and invalid device case, while still always returning hipErrorNotSupported

Unit_hipDeviceGetMemPool_Negative_Parameters

• Issue: function is not implemented (not handling nullptr and invalid device cases)

• Solution: implemented function hipDeviceGetMemPool to handle nullptr case and invalid device case, while still always returning hipErrorNotSupported

Unit_hipDeviceGetSharedMemConfig_Negative_Parameters

• Issue: incorrect handling of nullptr case – it used NULLCHECK macro which returned “hipErrorInvalidHandle” instead of “hipErrorInvalidValue”

• Solution: Added manual nullptr check in function hipDeviceGetSharedMemConfig

Unit_hipDeviceGetUuid_Negative

• Issue: function is not implemented (not handling nullptr and invalid device cases)

• Solution: implemented function hipDeviceGetUuid to handle nullptr case and invalid device case, while still always returning hipErrorNotSupported

Unit_hipDeviceSetMemPool_Negative_Parameters

• Issue: does not accept getDefaultMemPool not supported

• Solution: might need change of test

Unit_hipDriverGetVersion_Negative

• Issue: no handling of nullptr case

• Solution: added nullptr check

• New Issue: mismatch between expected value and returned value (400==1)

• Solution: not sure where hipErrorInvalidHandle is being returned so need to investigate further.
