net/smc: put slot when connection is killed
To get a send slot smc_wr_tx_get_free_slot() is called, which might wait for a free slot. When smc_wr_tx_get_free_slot() returns there is a check if the connection was killed in the meantime. In that case don't only return an error, but also put back the free slot.
