net: fsl: Fix error checking for platform_get_irq()
The gianfar driver has recently been enabled on arm64 but fails to build since it check the return value of platform_get_irq() against NO_IRQ. Fix this by instead checking for a negative error code. Even on ARM where this code was previously being built this check was incorrect since platform_get_irq() returns a negative error code which may not be exactly the (unsigned int)(-1) that NO_IRQ is defined to be.
