[PATCH] x86: amd_iommu.c prealloc_protection_domains should bestatic

[Jaswinder Singh Rajput]

Impact: cleanup, reduce kernel size a bit, avoid sparse warning

Fixes sparse warning:
arch/x86/kernel/amd_iommu.c:1299:6: warning: symbol 'prealloc_protection_domains' was not declared. Should it be static?
