can: c_can: don't indicate triple sampling support for D_CAN

BugLink: http://bugs.launchpad.net/bugs/1732726
commit fb5f0b3ef69b95e665e4bbe8a3de7201f09f1071 upstream.

The D_CAN controller doesn't provide a triple sampling mode, so don't set
the CAN_CTRLMODE_3_SAMPLES flag in ctrlmode_supported. Currently enabling
triple sampling is a no-op.
