rpmsg: virtio: Remove uncallable offchannel functions

The virtio_rpmsg_send_offchannel() and virtio_rpmsg_trysend_offchannel()
are wired up to the send_offchannel and trysend_offchannel members
of rpmsg_endpoint_ops, the only dereference of those was by
the unused, and now removed rpmsg_send_offchannel() and
rpmsg_trysend_offchannel() functions.

Remove them.
