xen/x86: eliminate nesting of run-queue locks inside xtime_lock

From: Zdenek Salvet <salvet@ics.muni.cz>

According to Debian bug 591362 this has been causing problems. While
no proof was given that the inverse lock order does actually occur
anywhere (with interrupts enabled), it is plain unnecessary to take
the risk.
