CHROMIUM: ARM: exynos: no duplicate mask/unmask in eint0_15

chained_irq_enter/exit() already mask&ack/unmask the chained interrupt.
There is no need to also explicitly do it in the handler.

Signed-off-by: Daniel Kurtz <djkurtz@chromium.org>
BUG=chrome-os-partner:13488
TEST=Manually verify.
TEST=ftrace shows only one call to
     combiner_{mask,unmask}_irq per call to exynos_irq_eint0_15
