net: tundra: tsi108: use spin_lock_irqsave instead of spin_lock_irq in IRQ context

BugLink: https://bugs.launchpad.net/bugs/1843463
[ Upstream commit 8c25d0887a8bd0e1ca2074ac0c6dff173787a83b ]

As spin_unlock_irq will enable interrupts.
Function tsi108_stat_carry is called from interrupt handler tsi108_irq.
Interrupts are enabled in interrupt handler.
Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_(un)lock_irq
in IRQ context to avoid this.
