Subject: [PATCH 22/32] media: ipu3-cio2: 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:
./pci/intel/ipu3/ipu3-cio2.c:318:19-26: WARNING: Consider using %pe to print PTR_ERR()
