can: add limit for nframes and clean up signed/unsigned variables
This patch adds a limit for nframes as the number of frames in TX_SETUP and RX_SETUP are derived from a single byte multiplex value by default. Use-cases that would require to send/filter more than 256 CAN frames should be implemented in userspace for complexity reasons anyway. Additionally the assignments of unsigned values from userspace to signed values in kernelspace and vice versa are fixed by using unsigned values in kernelspace consistently.
