Subject: [PATCH 4.19 50/99] vfio/pci: use correct format characters

[ Upstream commit 426b046b748d1f47e096e05bdcc6fb4172791307 ]

When compiling with -Wformat, clang emits the following warnings:

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for unsigned ints.
