Subject: [PATCH] RDS: IB: ensure an initialized ret is printed in pr_warn message

From: Colin Ian King <colin.king@...onical.com>

There is a path where ibmr is null and ret has not been initialized
and hence a pr_warn message is printing an uninitialized value in
ret.  Fix this by initializing ret to zero.

Detected by CoverityScan, CID#1357946 ("Uninitialized scalar variable")
