Commit 9d23a9818cb1 ("can: c_can: Remove unused inline function") left
behind C_CAN_MSG_OBJ_TX_LAST constant.

Commit fa39b54ccf28 ("can: c_can: Get rid of pointless interrupts") left
behind C_CAN_MSG_RX_LOW_LAST and C_CAN_MSG_OBJ_RX_SPLIT constants.

The removed code also made a comment useless and misleading.
