Subject: [PATCH v2 RESEND 4/5] s390/irq,nmi: include <asm/vtime.h> header directly

update_timer_sys() and update_timer_mcck() are inlines used for
CPU time accounting from the interrupt and machine-check handlers.
These routines are specific to s390 architecture, but included
via <linux/vtime.h> header implicitly. Avoid the extra loop and
include <asm/vtime.h> header directly.
