igb_uio: fix build on arm64 kernel

IGB_UIO compilation recently got enabled for ARM64 by default

The igb_uio compilation against ARM64 based stock 4.x (e.g. 4.13)
kernel is giving compilation warnings:

igb_uio.c: In function ‘igbuio_pci_irqcontrol’:
igb_uio.c:115:25: error: implicit declaration of function
‘irq_get_irq_dat ’ [-Werror=implicit-function-declaration]
  struct irq_data *irq = irq_get_irq_data(udev->info.irq);
                         ^
igb_uio.c:115:25: error: initialization makes pointer from integer without
a cast [-Werror=int-conversion]

Fixes: d196343a258e ("igb_uio: use kernel functions for masking MSI-X")
