mtd: rawnand: omap2: Fix check 0 for platform_get_irq()

Refer to commit a85a6c86c25b ("driver core: platform: Clarify that IRQ
0 is invalid"). Do not check 0 for platform_get_irq(), because
platform_get_irq() never return zero, and use the return error code of
platform_get_irq() instead of -ENODEV.
