irqchip/loongarch-cpu: Fix return value of lpic_gsi_to_irq()
lpic_gsi_to_irq() should return a valid Linux interrupt number if
acpi_register_gsi() succeeds, and return 0 otherwise. But lpic_gsi_to_irq()
converts a negative return value of acpi_register_gsi() to a positive value
silently.
Convert the return value explicitly.
