hw/intc: Fix LoongArch extioi coreisr accessing
1. When cpu read or write extioi COREISR reg, it should access
the reg belonged to itself, so the cpu index of 's->coreisr'
is current cpu number. Using MemTxAttrs' requester_id to get
the cpu index.
2. it need not to mask 0x1f when calculate the coreisr array index.
