net/smc: bugfix for smcr v2 server connect success statistic

Browse Source 
[ Upstream commit 6912e72483 ]

In the macro SMC_STAT_SERV_SUCC_INC, the smcd_version is used
to determin whether to increase the v1 statistic or the v2
statistic. It is correct for SMCD. But for SMCR, smcr_version
should be used.
