media: ar0521: 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:
./i2c/ar0521.c:1113:31-38: WARNING: Consider using %pe to print PTR_ERR()
