[dpdk-dev] [PATCH v4 4/8] pci: fix format warning on Windows

From: Tal Shnaiderman <talshn at mellanox.com>

the struct rte_pci_addr defines domain as uint32_t variable however
the PCI_PRI_FMT macro used for logging the struct sets the format
of domain to uint16_t.

The mismatch causes the following warning messages
in Windows clang build:

format specifies type 'unsigned short' but the argument
has type 'uint32_t' (aka 'unsigned int') [-Wformat]
