xen: remove stray preempt_disable() from PV AP startup code
In cpu_bringup() there is a call of preempt_disable() without a paired
preempt_enable(). This is not needed as interrupts are off initially.
Additionally this will result in early boot messages like:
BUG: scheduling while atomic: swapper/1/0/0x00000002
