RDS: IB: Limit the scope of has_fr/has_fmr variables
This patch fixes the scope of has_fr and has_fmr variables as they are needed only in rds_ib_add_one(). Signed-off-by: Avinash Repaka <avinash.repaka@oracle.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
