Sets the CAN receive timeout

Parameters:

dev	Pointer to the device structure
timeout	Timeout in milliseconds, NUT_WAIT_INFINITE = no time-out

Warning:: Timeout values are given in milliseconds and are limited to the granularity of the system timer. To disable timeout, set the parameter to NUT_WAIT_INFINITE.
