[PATCH 1/2] iio: imu: st_lsm6dsx: only set available_scan_masks if using device fifo

[Sean Nyekjaer <sean@geanix.com>]

We only need available scan_masks set if we are going to use the
onboard fifo. Unfortunately it requires the IRQ pins to be connected
to the SoC.
The next patch in this series add support for iio triggered buffer
for use with iio triggers.
