net/smc: no cursor update send in state SMC_INIT
If a writer blocked condition is received without data, the current
consumer cursor is immediately sent. Servers could already receive this
condition in state SMC_INIT without finished tx-setup. This patch
avoids sending a consumer cursor update in this case.
