can: add CAN_ERR_CNT flag to notify availability of error counter
Add a dedicated flag in uapi/linux/can/error.h to notify the userland that fields data[6] and data[7] of the CAN error frame were respectively populated with the tx and rx error counters. For all driver tree-wide, set up this flags whenever needed.
