[PATCH 4/7 v2] net: ethernet: i825xx: Fix platform_get_irq's error checking

[Arvind Yadav]

The platform_get_irq() function returns negative number if an error
occurs, Zero if No irq is found and positive number if irq gets successful.
platform_get_irq() error checking only for zero is not correct.
