media: samsung: exynos4-is: Use %pe format specifier

The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR().

This patch fixes this cocci report:
./platform/samsung/exynos4-is/media-dev.c:1337:16-23: WARNING: Consider using %pe to print PTR_ERR()
