irqchip/alpine-msi: Fix off-by-one in allocation error path
[ Upstream commitff3669a71a
] When alpine_msix_gic_domain_alloc() fails, there is an off-by-one in the number of interrupts to be freed. Fix it by passing the number of successfully allocated interrupts, instead of the relative index of the last allocated one. Fixes:3841245e84
