net/smc: use sk_rcvbuf as start for rmb creation

Commit 3e03472 ("net/smc: common functions for RMBs and send buffers") merged handling of SMC receive and send buffers. It introduced sk_buf_size as merged start value for size determination. But since sk_buf_size is not used at all, sk_sndbuf is erroneously used as start for rmb creation. This patch makes sure, sk_buf_size is really used as intended, and sk_rcvbuf is used as start value for rmb creation.
