[PATCH v2] loongson-3/hpet.c: remove IRQF_DISABLED flag

The IRQF_DISABLED is a NOOP and scheduled to be removed. According to
commit e58aa3d2d0cc (genirq: Run irq handlers with interrupts disabled)
running IRQ handlers with interrupts enabled can cause stack overflows
when the interrupt line of the issuing device is still active.
