[rds-devel] [PATCH] RDS: IB: ensure an initialized ret is printed in pr_warn message

[Colin King]

From: Colin Ian King <colin.king at canonical.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.
