udp6: Convey transmit path errors to the caller.
The transport layer's functional interface foresees having error codes percolate back up to the caller. However, up until now, the udp6 module simply returned -1 for any error. This patch lets the code return the specific error instead. Signed-off-by: Richard Cochran <richardcochran@gmail.com>master
