Dinghao Liu 2a21faa9c5 iommu/intel: Fix memleak in intel_irq_remapping_alloc 
commit ff2b46d7cf upstream.

When irq_domain_get_irq_data() or irqd_cfg() fails
at i == 0, data allocated by kzalloc() has not been
freed before returning, which leads to memleak.

Fixes: b106ee63ab ("irq_remapping/vt-d: Enhance Intel IR driver to support hierarchical irqdomains")
