RDS: IB: change rds_ib_active_bonding_excl_ips to only RFC3927 space

Currently rds_ib_active_bonding_excl_ips excludes both
169.254.0.0/16 and 172.10.0.0/16 address ranges from use with RDS
bonding. This parameter was meant to default to the range used by
link-local addresses (169.254.0.0/16, RFC3927) as those do not play
nicely with InfiniBand.

"172.10/16" was probably a mistaken typing of "172.16/12", which is
one of the private use -- but not link-local -- ranges defined by
RFC1918. 172.10.0.0/16 is in active use on the global Internet
(part of the block 172.0.0.0/12 as of this writing); it doesn't
belong here.

Change the parameter default to only "169.254/16" per the original
change's intent.
