lib/iscsi: Separate split and non-split in process_non_read_task_completion()

Browse Source 
In process_non_read_task_completion(), when the current I/O is
not split, we have to call only spdk_iscsi_task_response().

The next patch will fix the github issue by changing the path
executed when the current I/O is split.

Hence to make the fix easier, this patch separates split case and
non-split case.
