iscsi: Don't use error_is_set() to suppress additional errors
Using error_is_set(errp) that way can sweep programming errors under
the carpet when we get called incorrectly with an error set.
Commit 24d3bd6 added a broken error path to iscsi_do_inquiry(): it
first calls error_setg(), then jumps to the preexisting error label,
where error_setg() gets called again, triggering an assertion failure.
Commit cbee81f fixed this by guarding the second error_setg() with an
error_is_set().
Replace this fix by a simpler and safer one: jump right behind the
second error_setg().
