hw/intc/arm_gicv3_its: Check indexes before use, not after
In a few places in the ITS command handling functions, we were
doing the range-check of an event ID or device ID only after using
it as a table index; move the checks to before the uses.
This misordering wouldn't have very bad effects because the
tables are in guest memory anyway.
