Todd Broch 479aa8b1bc ec_uartd: bugfix for buffer pointer on partial write to FD. ...

Previously I neglected to increment the buffer pointer which would
allow double writing of same data and exclude tail if write didn't
complete in one call.

Also fixing bug with EAGAIN/EWOULDBLOCK to retry in those cases.
Previously we'd just have just failed for those errno values.
