In Linux kernel v5.18, "pci-dma-compat.h" wrapper file is removed [1].
Some APIs in that wrapper file were used by igb_uio kernel module and
kernel module build fails after mentioned commit.
Fixed build for v5.18 by replacing APIs in igb_uio.
Replaced APIs are available in Linux v4.4 (minimum Linux kernel version
supported by DPDK), so no Linux version check is needed.
