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.
