service-am: Handle panic conditions in SetTerminateResult

- Prevents propagation of panic conditions when setting termination results
- Previously, panic error codes could trigger cascading crashes
- Only stores non-error termination results while allowing successful completion
- Fixes crash when applications set panic-related termination codes (0x1A80A)
