iio: st_sensors: handle memory allocation failure to fix null pointer dereference

A null pointer deference on pdata can occur if the allocation of
pdata fails.  Fix this by adding a null pointer check and handle
the -ENOMEM failure in the caller.

Addresses-Coverity: ("Dereference null return value")
Fixes: 3ce85cc4fbb7 ("iio: st_sensors: get platform data from device tree")
