[ALSA] ali5451 - Code clean up, irq handler fix
- Clean up ali5451.c, following the standard coding style, unneeded codes reduced, and removal of redundant variable initializations. Hungarian notation isn't fixed yet ;) - Fix irq handler to return IRQ_NONE properly for shared irqs. Also check the hardware availability in irq handler to avoid possible initialization races at loading the driver.
