[PATCH] irqchip/sifive-plic: One function call less in __plic_init() after error detection

The kfree() function was called in one case by the
__plic_init() function during error handling
even if the passed data structure member contained a null pointer.
This issue was detected by using the Coccinelle software.

Thus use an other label.
