net/smc: short wait for late smc_clc_wait_msg
After sending one of the initial LLC messages CONFIRM LINK or ADD LINK, there is already a wait for the LLC response. It does not make sense to wait another long time for a CLC DECLINE. Thus this patch introduces a shorter wait time for these cases. Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
