Thanks Did. If you write that as an answer, I'll be able to credit you.

comment Expected time to absorption
I see. Very clever of you to construct a new DTMC and look at that. But the trick of $T_{\{1 \to (0,N)\}} = T_{\{(0,N) \to (0,N)\}}- T_{\{(0,N) \to 1\}}$ was key. Thanks for helping.

comment Expected time to absorption
@Brent: It means that the states $\{1,2,...,N-1\}$ are transient and they form a communicating class. Let me know if these terms are unfamiliar since they are standard in Markov chains.

comment Is linear function convex or concave?
Exactly my point. To prove convexity, you simply pick the coefficients as mentioned above. Convexity requires that coefficints be in $[0,1]$. Linearity covers this and far more!! That too with equality.
