x86/irq_remapping: Sanitize posted_msi_supported()x86/irq
posted_msi_supported() is a misnomer as it actually checks whether it is
enabled or not. Aside of that this does not take CONFIG_X86_POSTED_MSI into
account which is required to actually use it.
Rename it to posted_msi_enabled() and make the return value depend on
CONFIG_X86_POSTED_MSI, which allows the compiler to eliminate the related
dead code and data if disabled:
