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

Browse source 
commit ff3c664505 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.

Fixes: 31f614edb7 ('irqchip: armada-370-xp: implement MSI support')
