build fails for non-DIAGNOSTIC kernel with awingpio(4)



Hi,

Build fails for non-DIAGNOSTIC kernel with awingpio(4):

src/sys/arch/arm/allwinner/awin_gpio.c: In function 'awin_gpio_pin_irqen':
src/sys/arch/arm/allwinner/awin_gpio.c:937:37: error: unused variable 'grp' [-Werror=unused-variable]
  struct awin_gpio_pin_group * const grp = cookie;
                                     ^

This is because variable "grp" is only used as an argument for
KASSERT(9). Please apply the attached patch.

Thanks,
Rin
