net/smc: enable fallback for connection abort in state INIT
If a linkgroup is terminated abnormally already due to failing LLC CONFIRM LINK or LLC ADD LINK, fallback to TCP is still possible. In this case do not switch to state SMC_PEERABORTWAIT and do not set sk_err. Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
