iscsitarget: update patch to contain changes required to build with only linux v4.8 and above

1. Removes lines related "LINUX_VERSION_CODE >= KERNEL_VERSION(4, 3, 0)",
   as they are included in recent
   build_with_updated_bio_struct_of_linux_v4.3_and_above.patch.

2. Updated incorrect "#if 0//LINUX_VERSION_CODE >= KERNEL_VERSION(4, 8, 0)" line.

3. Updated patch to have in compliance with recent
   build_with_updated_bio_struct_of_linux_v4.3_and_above.patch.
