Subject: IB/iser: Delete an unnecessary variable initialisation in
 iser_send_data_out()
Patch-mainline: v4.16-rc1
Git-commit: d769e6be246cd811b4d467b77d5ff81a09450678
References: bsc#1103992 FATE#326009

The variable "tx_desc" will be set to an appropriate pointer a bit later.
Thus omit the explicit initialisation at the beginning.
