ext	struct dvb_extension_descriptor pointer
desc	pointer to struct dvb_desc to be allocated and filled

This function allocates a the descriptor and fills the fields inside the struct. It also makes sure that all fields will follow the CPU endianness. Due to that, the content of the buffer may change.

Returns: On success, it returns the size of the allocated struct. A negative value indicates an error.
