pata_ipx4xx_cf: Fix unsigned comparison with less than zero
[ Upstream commit c38ae56ee034623c59e39c0130ca0dec086c1a39 ]
The return from the call to platform_get_irq() is int, it can be
a negative error code, however this is being assigned to an unsigned
int variable 'irq', so making 'irq' an int, and change the position to
keep the code format.
