irqchip/riscv-intc: Prevent memory leak when riscv_intc_init_common() fails
[ Upstream commit 0110c4b110477bb1f19b0d02361846be7ab08300 ]
When riscv_intc_init_common() fails, the firmware node allocated is not
freed. Add the missing free().
Fixes: 7023b9d83f03 ("irqchip/riscv-intc: Add ACPI support")
