vfio/pci: Fix vfio_rtl8168_quirk_data_read address offset
Introductory comment for rtl8168 VFIO MSI-X quirk states:
At BAR2 offset 0x70 there is a dword data register,
offset 0x74 is a dword address register.
vfio: vfio_bar_read(0000:05:00.0:BAR2+0x70, 4) = 0xfee00398 // read data
Thus, correct offset for data read is 0x70,
but function vfio_rtl8168_quirk_data_read() wrongfully uses offset 0x74.
