Subject: [PATCH] irq_remapping/vt-d: Init all MSI entries not just the first
 one

Commit b106ee63abcc ("irq_remapping/vt-d: Enhance Intel IR driver to
support hierarchical irqdomains") caused a regression, which forgot
to initialize remapping data structures other than the first entry
when setting up remapping entries for multiple MSIs.
