[PATCH dpdk-kmods] linux/igb_uio: Adjust functions to the current kernel API

[PATCH dpdk-kmods] linux/igb_uio: Adjust functions to the current kernel API

[Leonid Bloch]

After commit 7968778914e53788a01c2dee2692cab157de9ac0 in the upstream
kernel (v5.18+) The functions pci_set_dma_mask() and
pci_set_consistent_dma_mask() are deprecated. Replacing them with the
new substitute (to avoid a compilation error).
