mv643xx_eth: fix inconsistent lock semantics
Nicolas Pitre noted that mv643xx_eth_poll was incorrectly using non-IRQ-safe locks while checking whether to wake up the netdevice's transmit queue. Convert the locking to *_irq() variants, since we are running from softirq context where interrupts are enabled. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
