Remove protocol version request IOCTL from UAPI
The current implementation of the protocol version request IOCTL call
doesn't return any version information and the protocol version is not
needed by any userspace program as it's for the communication between
the Linux kernel NPU driver and firmware. The IOCTL call has therefore
been removed from the UAPI and the inference runner has been updated
accordingly.
