x86, xen: fix hardirq.h merge fallout
Impact: build fix
This build error:
arch/x86/xen/suspend.c:22: error: implicit declaration of function 'fix_to_virt'
arch/x86/xen/suspend.c:22: error: 'FIX_PARAVIRT_BOOTMAP' undeclared (first use in this function)
arch/x86/xen/suspend.c:22: error: (Each undeclared identifier is reported only once
arch/x86/xen/suspend.c:22: error: for each function it appears in.)
triggers because the hardirq.h unification removed an implicit fixmap.h
include - on which arch/x86/xen/suspend.c depended. Add the fixmap.h
include explicitly.
