cuda.c: fix CUDA_PACKET response packet format

Browse Source 
According to comments in MOL, the response to a CUDA_PACKET should be one of
the following:

Reply: (CUDA_PACKET, status, cmd)
Error: (ERROR_PACKET, status, CUDA_PACKET, cmd)

Update cuda_receive_packet() accordingly to reflect this in order to make
MacOS 9 happy.
