Subject: irqchip: armada-370-xp: Fix releasing of MSIs

From: Neil Greatorex <neil@xxxxxxxxxxxxxxx>

commit ff3c664505bf8a8334bca5045e87b85cfe4d2277 upstream.

Store the value of d->hwirq in a local variable as the real value is wiped out
by calling irq_dispose_mapping. Without this patch, the armada_370_xp_free_msi
function would always free MSI#0, no matter what was passed to it.
