Improved implementations for sceKernelDebugRaiseException functions

Browse Source 
These functions take in two parameters, an error code and some other value that I have no idea what is for. If that second parameter is not zero, they return ORBIS_KERNEL_ERROR_EINVAL before any calls to mdbg_service.
These improved implementations add the early error return and a message with the error code to the unreachable.
