staging: comedi: adv_pci1710: fix AI channels 16-31 for PCI-1713
commit a9d3a9cedc1330c720e0ddde1978a8e7771da5ab upstream.
The Advantech PCI-1713 has 32 analog input channels, but an incorrect
bit-mask in the definition of the `PCI171X_MUX_CHANH(x)` and
PCI171X_MUX_CHANL(x)` macros is causing channels 16 to 31 to be aliases
of channels 0 to 15. Change the bit-mask value from 0xf to 0xff to fix
it. Note that the channel numbers will have been range checked already,
so the bit-mask isn't really needed.
