[PATCH net-next 1/7] net/smc: reset cursor update required flag

[Ursula Braun]

From: Karsten Graul <kgr...@linux.ibm.com>

When an updated rx_cursor_confirmed field was sent to the peer then
reset the cons_curs_upd_req flag. And remove the duplicate reset and
cursor update in smc_tx_consumer_update().
