Subject: iio: st_pressure: st_accel: pass correct platform data to init

From: Michael Nosthoff <committed@xxxxxxxx>

commit 8b438686a001db64c21782d04ef68111e53c45d9 upstream.

Commit 7383d44b added a pointer pdata which get set to the default
platform_data when non was defined in the device. But it did not
pass this pointer to the st_sensors_init_sensor call but still
used the maybe uninitialized platform_data from dev.

This breaks initialization when no platform_data is given and
the optional st,drdy-int-pin devicetree option is not set.

This commit fixes this.
