cputime: Separate irqtime accounting from generic vtime
vtime_account() doesn't have the same role in CONFIG_VIRT_CPU_ACCOUNTING and CONFIG_IRQ_TIME_ACCOUNTING. In the first case it handles time accounting in any context. In the second case it only handles irq time accounting. So when vtime_account() is called from outside vtime_account_irq_*() this call is pointless to CONFIG_IRQ_TIME_ACCOUNTING. To fix the confusion, change vtime_account() to irqtime_account_irq() in CONFIG_IRQ_TIME_ACCOUNTING. This way we ensure future account_vtime() calls won't waste useless cycles in the irqtime APIs.
