[PATCH v4 1/6] x86/irqflags: Fix build failure

[Juergen Gross <jgross@suse.com>]

Commit 22cc5ca5de52 ("x86/paravirt: Move halt paravirt calls under
CONFIG_PARAVIRT") moved some paravirt hooks from the CONFIG_PARAVIRT_XXL
umbrella to CONFIG_PARAVIRT, but missed to move the associated
"#include <asm/paravirt.h>" in irqflags.h from CONFIG_PARAVIRT_XXL to
CONFIG_PARAVIRT.

This hasn't resulted in build failures yet, as all use cases of
irqflags.h had paravirt.h included via other header files, even without
CONFIG_PARAVIRT_XXL being set.

In order to allow changing those other header files, e.g. by no longer
including paravirt.h, fix irqflags.h by moving inclusion of paravirt.h
under the CONFIG_PARAVIRT umbrella.
