irqchip/loongson-eiointc: Fix return value checking of eiointc_index
Return value of function eiointc_index is int, however it is converted
into uint32_t and then compared smaller than zero, this will cause logic
problem.
Fixes: dd281e1a1a93 ("irqchip: Add Loongson Extended I/O interrupt controller support")
