[PATCH 2/7 v2] net: ezchip: nps_enet: Fix platform_get_irq's error checking

[Arvind Yadav <arvind.yadav.cs@gmail.com>]

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.
