ARM: tegra: gpio: Fix unused variable warnings

Change b0f18edaf6ee4e6fac89cae63a90bd38ad2a3418 (arm: tegra: Remove unused bogus irq enable/disable magic) introduces warnings:
arch/arm/mach-tegra/gpio.c: In function 'tegra_gpio_resume':
arch/arm/mach-tegra/gpio.c:260: warning: unused variable 'i' arch/arm/mach-tegra/gpio.c: In function 'tegra_gpio_suspend':
arch/arm/mach-tegra/gpio.c:283: warning: unused variable 'i'

Fix them, and fix a coding style issue on the same lines.
