iio: accel: bma400: Fix smatch warning based on use of unintialized value.
Only specific bits in this value are ever used and those are initialized,
but that is complex to reason about in a checker. Hence, initialize
the value to zero and avoid the complexity.
Smatch warning:
drivers/iio/accel/bma400_core.c:1287 bma400_tap_event_en()
error: uninitialized symbol 'field_value'.
