Subject: [PATCH] x86/irqflags: Fix build failure

When building with CONFIG_PARAVIRT, but without CONFIG_PARAVIRT_XXL,
a build failure might happen due to arch/x86/include/asm/irqflags.h
only including asm/paravirt.h when CONFIG_PARAVIRT_XXL is set.

This was spotted when testing a patch removing the
"#include <asm/paravirt.h>" from another header.

Fixes: 22cc5ca5de52 ("x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202601152203.plJOoOEF-lkp@intel.com/
